send-pack: mark failure of atomic push properly

When pushing with SSH or other smart protocol, references are validated
by function `check_to_send_update()` before they are sent in commands
to `send_pack()` of "receve-pack".  For atomic push, if a reference is
rejected after the validation, only references pushed by user should be
marked as failure, instead of report failure on all remote references.

Commit v2.22.0-1-g3bca1e7f9f (transport-helper: enforce atomic in
push_refs_with_push, 2019-07-11) wanted to fix report issue of HTTP
protocol, but marked all remote references failure for atomic push.

In order to fix the issue of status report for SSH or other built-in
smart protocol, revert part of that commit and add additional status
for function `atomic_push_failure()`.  The additional status for it
except the "REF_STATUS_EXPECTING_REPORT" status are:

- REF_STATUS_NONE : Not marked as "REF_STATUS_EXPECTING_REPORT" yet.
- REF_STATUS_OK   : Assume OK for dryrun or status_report is disabled.

This fix won't resolve the issue of status report in transport-helper
for HTTP or other protocols, and breaks test case in t5541.  Will fix
it in additional commit.
