xfs_fsr had been broken due to restricting a RESVSP ioctl to root.
In fact, even root could not defrag other user's files because
it forked & did a setuid prior to calling the ioctl.
This fixes things up:

Remove forks from xfs_fsr.
Rather than forking & setuid to the file's owner, simply
run as root and chown the temp. defrag file to the original owner,
to keep quota in sync.  This lets root execute the RESVSP
ioctl as necessary, but keeps all quota info correct when defragging
another user's file.
