iget: stop FreeVXFS from using iget() and read_inode()
Stop the FreeVXFS filesystem from using iget() and read_inode(). Replace
vxfs_read_inode() with vxfs_iget(), and call that instead of iget().
vxfs_iget() then uses iget_locked() directly and returns a proper error code
instead of an inode in the event of an error.
vxfs_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.
