Subject: [PATCH -next] scsi: megaraid_sas: remove set but not used variable 'sge_sz'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/scsi/megaraid/megaraid_sas_base.c: In function megasas_create_frame_pool:
drivers/scsi/megaraid/megaraid_sas_base.c:4124:6: warning: variable sge_sz set but not used [-Wunused-but-set-variable]

It's not used any more since
commit 200aed582d61 ("megaraid_sas: endianness related bug fixes and code optimization")
