nfs41: sunrpc: xprt_alloc_bc_request() should not use spin_lock_bh()

xprt_alloc_bc_request() is always called in soft interrupt context.
Grab the spin_lock instead of the bottom half spin_lock.  Softirqs
do not preempt other softirqs running on the same processor, so there
is no need to disable bottom halves.
