[SCSI] megaraid: fix warnings when CONFIG_PROC_FS=n

drivers/scsi/megaraid.c: In function 'megaraid_probe_one':
drivers/scsi/megaraid.c:4893: warning: implicit declaration of function 'mega_create_proc_entry'
drivers/scsi/megaraid.c: In function 'megaraid_remove_one':
drivers/scsi/megaraid.c:4968: warning: unused variable 'buf'

Fix by adding #defines
