ATA_EHI_NO_AUTOPSY and ATA_EHI_QUIET are used to control the behavior of EH. As only the master link is visible outside EH, these flags are set only for the master link although they should also apply to the slave link, which causes spurious EH messages during probe and suspend/resume. This patch transfers those two flags to slave ehc.i before performing slave autopsy and reporting.
