[ Upstream commit 7e6b7e740addcea450041b5be8e42f0a4ceece0f ]

The call to pm8001_ccb_task_free() at the end of
pm8001_mpi_task_abort_resp() already frees the ccb tag. So when the device
NCQ_ABORT_ALL_FLAG is set, the tag should not be freed again.  Also change
the hardcoded 0xBFFFFFFF value to ~NCQ_ABORT_ALL_FLAG as it ought to be.
