xfs: test delalloc quota leak when chprojid fails

Browse Source 
This is a regression test for a bug in the XFS implementation of
FSSETXATTR.  When we try to change a file's project id, the quota
reservation code will update the incore quota reservations for delayed
allocation blocks.  Unfortunately, it does this before we finish
validating all the FSSETXATTR parameters, which means that if we decide
to bail out, we also fail to undo the incore changes.
