Daniel Gabay 675a1803ef wifi: iwlwifi: mvm: Use the sync timepoint API in suspend 
[ Upstream commit 9715246ca0 ]

When starting the suspend flow, HOST_D3_START triggers an _async_
firmware dump collection for debugging purposes. The async worker
may race with suspend flow and fail to get NIC access, resulting in
the following warning:
"Timeout waiting for hardware access (CSR_GP_CNTRL 0xffffffff)"

Fix this by switching to the sync version to ensure the dump
completes before proceeding with the suspend flow, avoiding
potential race issues.
