Subject: [PATCH -next] scsi: megaraid: Make local symbol 'megasas_debugfs_root' static

The sparse tool complains as follows:

drivers/scsi/megaraid/megaraid_sas_debugfs.c:45:15: warning: symbol 'megasas_debugfs_root' was not declared. Should it be static?

The `megasas_debugfs_root` symbol is not dereferenced
in drivers/scsi/megaraid/megaraid_sas_base.c any more,
remove the declaration here.

After that, the megasas_debugfs_root symbol is no used
any more except this file
(drivers/scsi/megaraid/megaraid_sas_debugfs.c), so
decorate it with `static`.
