Subject: [Intel-wired-lan] [PATCH iwl-net v2] ice: fix posted write support for sideband queue operations

On E830, PTP time adjustment commands sent via SBQ don't generate completion responses, causing the driver to timeout waiting and return -EIO, when trying:

phc_ctl eth8 get adj 2 get
dmesg: ice 0000:1a:00.0: PTP failed to adjust time, err -5

Add support for posted mode not to wait for completion response.

Fixes: 8f5ee3c477a8 ("ice: add support for sideband messages")
