scsi: qla2xxx: Fix mailbox Ch erroneous error

Browse source

Mailbox Ch/dump ram extend expects mb register 10 to be set. If not
set/clear, firmware can pick up garbage from previous invocation of this
mailbox. Example: mctp dump can set mb10.  On subsequent flash read which
use mailbox cmd Ch, mb10 can retain previous value.
