IB/cma: Make the code easier to verify
Static source code analysis tools like smatch cannot handle functions that lock or not lock a mutex depending on the value of the arguments. Hence inline the function cma_disable_callback(). Additionally, this patch realizes a small performance optimization by reducing the number of mutex_lock() and mutex_unlock() calls in the modified functions. With this patch applied smatch no longer complains about source file cma.c. Without this patch smatch reports the following for this source file: drivers/infiniband/core/cma.c:1959: cma_req_handler() warn: inconsistent returns 'mutex:&listen_id->handler_mutex'. Locked on: line 1880 line 1959 Unlocked on: line 1941 drivers/infiniband/core/cma.c:2112: iw_conn_req_handler() warn: inconsistent returns 'mutex:&listen_id->handler_mutex'.
