Subject: [PATCH] [SCSI] mpt2sas: Remove unused duplicate diag_buffer_enable
 param

Commit 921cd8024b90 ("[SCSI] mpt2sas: New feature - Fast Load
Support") moved handling of the diag_buffer_enable module parameter
from mpt2sas_base.c to mpt2sas_scsih.c, but it left an old copy of the
parameter in mpt2sas_base.c.  Remove the unused stub.
