No need to parse the mount option into a structure before applying it to
struct xfs_mount.

The content of xfs_start_flags gets merged into xfs_parseargs. Calls
inbetween don't care and can use mount members instead of the args struct.

This patch uncovered that the mount option for shared filesystems wasn't
ever exposed on Linux. The code to handle it is #if 0'ed in this patch
pending a decision on this feature. I'll send a writeup about it to the
list soon.

- * XFS arguments structure, constructed from the arguments we
- * are passed via the mount system call.
- *
- * NOTE: The mount system call is handled differently between
- * Linux and IRIX.  In IRIX we worked work with a binary data
- * structure coming in across the syscall interface from user
- * space (the mount userspace knows about each filesystem type
- * and the set of valid options for it, and converts the users
- * argument string into a binary structure _before_ making the
- * system call), and the ABI issues that this implies.
- *
- * In Linux, we are passed a comma separated set of options;
- * ie. a NULL terminated string of characters.  Userspace mount
- * code does not have any knowledge of mount options expected by
- * each filesystem type and so each filesystem parses its mount
- * options in kernel space.
- *
- * For the Linux port, we kept this structure pretty much intact
- * and use it internally (because the existing code groks it).
