[PATCH 5/8] scsi: qla2xxx: Remove unused qla82xx_wait_for_state_change

[linux@treblig.org]

From: "Dr. David Alan Gilbert" <linux@treblig.org>

qla82xx_wait_for_state_change() was added in 2010 as part of
commit 579d12b58abb ("[SCSI] qla2xxx: Added support for quiescence mode for
ISP82xx.")
but has remained unused.

Remove it.
