This patch fixes the checkpatch warning that else is not generally
useful after a break or return.

vfree frees the virtually continuous memory area starting at addr.
If addr is NULL, no operation is performed. So NULL test is not needed
before vfree.
This was done using Coccinelle:

rtw_AcceptAddbaReq is a static variable, it is set once and never
modified. It is referenced only once, to assign its value to a member
of struct registry_priv with practically the same name.
Get rid of the variable, and move the meaningful part of the comment
near the declaration of the relevant field of struct registry_priv.
Raises a new checkpatch issue, which is fixed in a later commit:

This adds support for monitoring IEEE 802.11 Data and Management frames
received or transmitted by a RTL8188EU-based device handled by this
driver.
The monitor interface is not enabled by default and will be registered
only if monitor_enable module parameter is set to 1. When enabled it
will show up as a monX network device, which can be used by the
userspace programs for monitoring network traffic.
It is intended as an exploratory/debugging tool for rtl8188eu driver.

Eliminate "space prohibited before that ','" errors found by checkpatch,
but do this only to lines which after the patch is applied do not
exceed 80 characters. Out of that only those lines are changed, whose
context does not exceed 80 characters in each line. In other words the
changes are limited to cases where the patch generated is itself
checkpatch-correct.

"If the name of a function is an action or an imperative command,
the function should return an error-code integer." (Documentation/CodingStyle)
Several action-like functions in this driver return a boolean: _SUCCESS = 1 on
success, _FAIL = 0 on error, defined in
drivers/staging/rtl8188eu/include/osdep_service.h.
Change rtw_start_drv_threads() to return a proper 0-or-error value.
