WenTao Liang 2c007acf7b scsi: elx: efct: Fix refcount leak in efct_hw_io_abort() 
When efct_hw_reqtag_alloc() fails in efct_hw_io_abort(), the error path
returns -ENOSPC without releasing the reference obtained via
kref_get_unless_zero() earlier in the function. All other error paths
correctly drop the reference. This causes a permanent reference leak on the
io_to_abort object.

Additionally, the abort_in_progress flag is left set to true on this path,
which means future abort attempts for the same I/O will immediately return
-EINPROGRESS even though the abort was never submitted, effectively
blocking recovery.

Fix this by adding the missing kref_put() call and reset abort_in_progress
to false, matching the cleanup done in the efct_hw_wq_write() failure path
below.
