[PATCH] xfs: test bad character in xfs_db field list selector string

[Zorro Lang <zlang@redhat.com>]

Bad characters likes tailing asterisk, slash or quote in xfs_db
field string can trigger a xfs_db crash. This bug has been fixed
by xfsprogs "945e47e2 xfs_db: fix crash when field list selector
string has trailing slash".
