convert: git cherry-pick -Xrenormalize did not work 

Working with a repo that used to be all CRLF. At some point it
was changed to all LF, with `text=auto` in .gitattributes.
Trying to cherry-pick a commit from before the switchover fails:

    $ git cherry-pick -Xrenormalize <commit>
    fatal: CRLF would be replaced by LF in [path]

Commit 65237284 "unify the "auto" handling of CRLF" introduced
a regression:

Whenever crlf_action is CRLF_TEXT_XXX and not CRLF_AUTO_XXX,
SAFE_CRLF_RENORMALIZE was feed into check_safe_crlf().  This is
wrong because here everything else than SAFE_CRLF_WARN is treated as
SAFE_CRLF_FAIL.

Call check_safe_crlf() only if checksafe is SAFE_CRLF_WARN or
SAFE_CRLF_FAIL.
