jfs: Set flags on quota files directly
Currently immutable and noatime flags on quota files are set by quota
code which requires us to copy inode->i_flags to our on disk version
of quota flags in GETFLAGS ioctl and copy_to_dinode(). Move to
setting / clearing these on-disk flags directly to save that copying.
