[PATCH] staging: rtl8723bs: use guard(mutex) in ips_enter()

[Ivy Lopez <skunkolee@gmail.com>]

Replace manual mutex_lock()/mutex_unlock() in ips_enter() with
guard(mutex) from linux/cleanup.h. This is a single-exit function
so the conversion is a direct drop-in and removes the need to
manually balance the unlock.
