agp: convert drivers/char/agp/frontend.c to use unlocked_ioctl

Browse Source 
As of now, agp_compat_ioctl already runs without the BKL.  Mutual exclusion
is enforced by agp_fe.agp_mutex in agp_ioctl() and agp_compat_ioctl().
Apply the same locking rationale to the two functions allowing BKL cleanup.
