scsi: qla2xxx: Fix MPI failure AEN (8200) handling
Today, upon an MPI failure AEN, on top of collecting an MPI dump, a regular
firmware dump is also taken and then chip reset. This is disruptive to IOs
and not required. Make the firmware dump collection, followed by chip
reset, optional (not done by default).
Firmware dump buffer and MPI dump buffer are independent of each
other with this change and each can have dump that was taken at two
different times for two different issues. The MPI dump is saved in a
separate buffer and is retrieved differently from firmware dump.
To collect full dump on MPI failure AEN, a module parameter is
introduced:
ql2xfulldump_on_mpifail (default: 0)
