[PATCH] exofs/super.c: local functions should be static

[H Hartley Sweeten <hartleys@visionengravers.com>]

This quiets the following sparse noise:

warning: symbol 'exofs_sync_fs' was not declared. Should it be static?
warning: symbol 'exofs_free_sbi' was not declared. Should it be static?
warning: symbol 'exofs_get_parent' was not declared. Should it be static?
