net/802/mrp: fix lockdep splat
commit fb745e9a037895 ("net/802/mrp: fix possible race condition when
calling mrp_pdu_queue()") introduced a lockdep splat.
[ 19.735147] =================================
[ 19.735235] [ INFO: inconsistent lock state ]
[ 19.735324] 3.9.2-build-0063 #4 Not tainted
[ 19.735412] ---------------------------------
[ 19.735500] inconsistent {IN-SOFTIRQ-W} -> {SOFTIRQ-ON-W} usage.
[ 19.735592] rmmod/1840 [HC0[0]:SC0[0]:HE1:SE1] takes:
[ 19.735682] (&(&app->lock)->rlock#2){+.?...}, at: [<f862bb5b>]
mrp_uninit_applicant+0x69/0xba [mrp]
app->lock is normally taken under softirq context, so disable BH to
avoid the splat.
