From: Prasad B Munirathnam prasad.munirathnam@microsemi.com

[ Upstream commit 5771cfffdffe709ae9b403b6f80438ca40bf850e ]

"FIB_CONTEXT_FLAG_TIMEDOUT" flag is set in aac_eh_abort to indicate command timeout. Using the same flag in reset handler causes the command to time out and the I/Os were dropped.

Define a new flag "FIB_CONTEXT_FLAG_EH_RESET" to make sure I/O is properly handled in eh_reset handler.

[mkp: tweaked commit message]
