Greg Edwards ce7c6c9e1d mpt3sas: Fix resume on WarpDrive flash cards
mpt3sas crashes on resume after suspend with WarpDrive flash cards.  The
reply_post_host_index array is not set back up after the resume, and we
deference a stale pointer in _base_interrupt().

Move the reply_post_host_index array setup into
mpt3sas_base_map_resources(), which is also in the resume path.
