[SCSI] mpt2sas: Raid 10 Volume is showing as Raid 1E in dmesg 

This patch modifies the slave_configure callback so the messages that get sent
to system log for RAID1E volumes contain the string "RAID10" instead of
"RAID1E". These messages contain information regarding what kind of scsi device
is being added. Certain OEMS can enable displaying the RAID10 string instead of
RAID1E via manufacturing page 10.   The driver will read this config page at
driver load time, then determine from the GenericFlags0 bits whether display
the RAID10 or RAID1E string, also even drive count is taken into consideration.
