[PATCH] scsi: qla2xxx: Fix memory leak in __qlt_24xx_handle_abts()

[Rafael Mendonca <rafaelmendsr@gmail.com>]

Commit 8f394da36a36 ("scsi: qla2xxx: Drop TARGET_SCF_LOOKUP_LUN_FROM_TAG")
made the __qlt_24xx_handle_abts() function return early if
tcm_qla2xxx_find_cmd_by_tag() doesn't find a command, but it missed to
clean up the allocated memory for the management command in such a case.

Fixes: 8f394da36a36 ("scsi: qla2xxx: Drop TARGET_SCF_LOOKUP_LUN_FROM_TAG")
