crlf: do not ignore GIT_PASSTHROUGH error When no payload is set for `crlf_apply` we try to compute the crlf attributes ourselves with `crlf_check`. When the function determines that the current file does not require any treatment we return the GIT_PASSTHROUGH error code without actually allocating the out-pointer, which indicates the file should not be passed through the filter. The `crlf_apply` function explicitly checks for the GIT_PASSTHROUGH return code and ignores it. This means we will try to apply the crlf-filter to the current file, leading us to dereference the unallocated payload-pointer. Fix this obviously incorrect behavior by not treating GIT_PASSTHROUGH in any special way. This is the correct thing to do anyway, as the code indicates that the file should not be passed through the filter.
