scsi: mpt3sas: Fix mpt3sas_check_same_4gb_region() kdoc comment

The start_addres argument of mpt3sas_check_same_4gb_region() was misnamed
in the function kdoc comment, resulting in the following warning when
compiling with W=1.

drivers/scsi/mpt3sas/mpt3sas_base.c:5728: warning: Function parameter or
member 'start_address' not described in 'mpt3sas_check_same_4gb_region'
drivers/scsi/mpt3sas/mpt3sas_base.c:5728: warning: Excess function
parameter 'reply_pool_start_address' description in
'mpt3sas_check_same_4gb_region'

Fix the argument name in the function kdoc comment to avoid it. While at
it, remove a useless blank line between the kdoc and function code.
