Sebastian Sanchez 9b86071c5e IB/hfi1: Remove critical section gap in sc_buffer_alloc() 
In sc_buffer_alloc(), the sc->alloc_lock is released
before calling sc_release_update(), and it is reacquired
after the function call. This causes CPU lock trading.
Fix it by not dropping the lock before calling
sc_release_update().
