Ralph Boehme bf04ca5658 s3/locking: prime flags in a fresh sharemode data object 
This is needed to prime the logic in share_mode_flags_restrict() for the
following scenario:

* (First) CREATE on a file with FILE_SHARE_NONE and
  access_mask=FILE_READ_ATTRIBUTES (a stat-open).

* share_mode_flags_restrict() gets called with

    share_mode_flags_restrict(flags=0,
                              access_mask=0x80,
                              share_mode=0,
                              lease_type=UINT32_MAX)

  and returns a value where none of the FILE_SHARE_* flags is set.

As a result share_mode_data.flags doesn't reflect the share-modes in effect.

This doesn't change any current visible behaviour outside of open_mode_check(),
but it avoids calling share_mode_forall_entries() in open_mode_check_fn().
