mpt2sas, mpt3sas: fix upper bound for the module parameter max_sgl_entries
Change Set:
1. Extended the upper boundary restriction for the module parameter
max_sgl_entries. Earlier, the max_sgl_entries was capped at the
SCSI_MAX_SG_SEGMENTS kernel definition. With this change, the user
would be able to set the max_sgl_entries to any value which is
greater than SCSI_MAX_SG_SEGMENTS and less than the minimum of
SCSI_MAX_SG_CHAIN_SEGMENTS & hardware limit (Calculated using
IOCFacts's MaxChainDepth).
2. Added a print for the message log whenever the user sets the
max_sgl_entries to a value greater than SCSI_MAX_SG_SEGMENTS to
warn about the kernel definition overriding.
