Subject: [PATCH 07/13] aacraid: move scsi_(block,unblock)_requests out of _aac_reset_adapter()
EXTERNAL EMAIL: Do not click links or open attachments unless you know the content is safe
_aac_reset_adapter() only has one caller, and that one already calls scsi_block_requests(). So move the calls out of _aac_reset_adapter() to avoid calling scsi_block_requests() twice.
