[SCSI] qla2xxx: Correct SRB usage-after-completion/free issues.
The driver is incorrectly assuming that the 'sp' reference held
in qla2[x00|4xx]_abort_command() is valid after the mailbox
command is issued to abort the exchange. It is *not*, as the
command may be completed during interrupt context before control
is returned to the mailbox caller.
