Subject: [PATCH] [SCSI] mptfusion: fix compilation warning

Function seq_mpt_print_ioc_summary is invoked only from functions that
depend on CONFIG_PROC_FS.  This commit makes this function also depend
on this configuration.  Also removes function forward declaration.

It fixes the following warning:

drivers/message/fusion/mptbase.c:6884:13: warning: 'seq_mpt_print_ioc_summary' defined but not used [-Wunused-function]
