ipc: uninline some code from util.h

ipc_lock_check_down(), ipc_lock_check() and ipcget() seem too large to be
inline.  Besides, they give no optimization being inline as they perform
calls inside in any case.

Moving them into ipc/util.c saves 500 bytes of vmlinux and shortens IPC
internal API.

The ipcget() growth is the result of gcc inlining of currently static
ipcget_new/_public.
