50120c37b3 scst_cmd_aborted() is a bad and ambiguous name. Rename it to scst_cmd_aborted_on_xmit() and create a new version, which truly reflects its semantic.

6e55334a9f ib_srpt: Fix QP use-after-free triggered by SRP logout. 
Fixed this by destroying cm_id before QP instead of after. The following
messages were logged if the use-after-free occurred:

mlx4_core 0000:08:00.0: command 0x19 failed: fw status = 0x9
ib_srpt: ***ERROR***: srpt_init_ch_qp() failed (-9)
ib_srpt: ***ERROR***: rejected SRP_LOGIN_REQ because creating a new RDMA channel failed.
