scsi: mpi3mr: Fix corrupt config pages PHY state is switched in sysfs
The driver, through the SAS transport, exposes a sysfs interface to
enable/disable PHYs in a controller/expander setup. When multiple PHYs
are disabled and enabled in rapid succession, the persistent and current
config pages related to SAS IO unit/SAS Expander pages could get
corrupted.
Use separate memory for each config request.
