[PATCH] net: ax25: replace bh_lock_sock with lock_sock_fast in ax25_rt_autobind

ax25_rt_autobind is always called in user context, so lock_sock_fast should be used, and bh_lock_sock should only be used in BH context this replacement fixes a possible deadlock inconsistent {SOFTIRQ-ON-W} -> {IN-SOFTIRQ-W} usage. ksoftirqd/1/16 [HC0[0]:SC1[1]:HE1:SE0] takes: 8282a7d4
