USB: uas: Rename sense pipe and sense urb to status pipe and status urb
The spec calls this the status pipe. While it is used to receive sense IUs, it is also used to receive other IUs, so this can be confusing. Reported-by: Luben Tuikov <ltuikov@yahoo.com> Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
