[PATCH] minor fixup of quota checking

[Andreas Dilger]

The following patch fixes (I think) an error in the boolean logic for
checking if a filesystem can support quotas.  Since quotas use both
read and write file operations, we need both functions available, but
the current test only fails if both read and write are NOT available.

Cheers, Andreas
