mesh_sync_offset_adjust_tbtt() implements Extensible synchronization

not operate the flag "TBTT Adjusting subfield" ([1] 8.4.2.100.8 Mesh
Capability), since it is used only for MBCA ([1] 13.13.4 Mesh beacon
collision avoidance, see 13.13.4.4.3 TBTT scanning and adjustment
procedures for detail). So this patch remove the flag operations.

802.11-2012 13.13.2.2.3:

The mesh STA checks if the transmitter of the Beacon frame or Probe
Response frame is in the
process of the TBTT adjustment (see 13.13.4.4.3). If the received
frame contains the Mesh
Configuration element and the TBTT Adjusting subfield in the Mesh
Configuration field is 1, the
mesh STA shall invalidate the T offset value for this neighbor STA and
shall not perform the
following steps.

so, no? I think we need to indicate a TSF adjustment is taking place.
