nfsd4: it's OK to return nfserr_symlink
The nfsd4 code has a bunch of special exceptions for error returns which
map nfserr_symlink to other errors.
In fact, the spec makes it clear that nfserr_symlink is to be preferred
over less specific errors where possible.
The patch that introduced it back in 2.6.4 is "kNFSd: correct symlink
related error returns.", which claims that these special exceptions are
represent an NFSv4 break from v2/v3 tradition--when in fact the symlink
error was introduced with v4.
I suspect what happened was pynfs tests were written that were overly
faithful to the (known-incomplete) rfc3530 error return lists, and then
code was fixed up mindlessly to make the tests pass.
Delete these unnecessary exceptions.
