scsi: qla2xxx: Remove WARN_ON_ONCE in qla2x00_status_cont_entry() 

Commit 88263208dd ("scsi: qla2xxx: Complain if sp->done() is not called
from the completion path") introduced the WARN_ON_ONCE in
qla2x00_status_cont_entry(). The assumption was that there is only one
status continuations element. According to the firmware documentation it is
possible that multiple status continuations are emitted by the firmware.

Fixes: 88263208dd ("scsi: qla2xxx: Complain if sp->done() is not called from the completion path")
