[SCSI] mptfusion: firmware download boot fix's
Fix's to insure download boot could occur when either channel of 1030 is reset. Necessary in order for onboard controller in flashless environment to become operational. Signed-off-by: Eric Moore <Eric.Moore@lsil.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
