f2fs: add default mount options to remount
I use f2fs filesystem with /data partition on my Android phone by the default mount options. When I remount /data in order to adding discard option to run some benchmarks, I find the default options such as background_gc, user_xattr and acl turned off. So I introduce a function named default_options in super.c. It do some default setting, and both mount and remount operations will call this function to complete default setting.
