Fix oops on directory read error

This should fix the oops in xfs_do_da_buf() as a result of running out of
vmalloc space. It won't fix the vmalloc problem, but should allow the system to
continue to operate. Note that instead of a crash, it is likely that a
controlled filesystem shutdown will now result when vmalloc space is exhausted
in these situations....
