[GFS2] Fix bug in error path of inode
This fixes a bug in the ordering of operations in the error path of
createi. Its not valid to do an iput() when holding the inode's glock
since the iput() will (in this case) result in delete_inode() being
called which needs to grab the lock itself. This was causing the
recursive lock checking code to trigger.
