In mdc_close(), if mdc_fid_alloc() fails, we should remember this error code, therefore if close REQ finishes successfully, that error code should be returned upper layer to LLITE to indicate why release failed.

We need to land patch: http://review.whamcloud.com/6794 for HSM so that ll_data_version() can drop all caching pages before doing release.
