iget: stop UFS from using iget() and read_inode()

Browse Source 
Stop the UFS filesystem from using iget() and read_inode().  Replace
ufs_read_inode() with ufs_iget(), and call that instead of iget().  ufs_iget()
then uses iget_locked() directly and returns a proper error code instead of an
inode in the event of an error.

ufs_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.
