[PATCH] nfsd: remove unneeded EEXIST error check in nfsd_do_file_acquire

[Jeff Layton]

Given that we do the search and insertion while holding the i_lock, I
don't think it's possible for us to get EEXIST here. Remove this case.

This is replacement for PATCH 1/3 in the series I sent yesterday. I
think it makes sense to just eliminate this case.
