HAL: HAL: Increase netlink event socket buffer to avoid dropping packet
Intermittenly, we can see "No buffer space available" in log.
06-15 13:34:00.495 E WifiHAL : POLL Error; error no = 0 (Success)
06-15 13:34:00.495 E WifiHAL : Read after POLL returned -1, error no = 105 (No buffer space available)
We increased the socket buffer in vendor HAL before. pa/1835219
At that time, 2MB socket buffer is enough to handle debug_dump (2M~4M) and other events.
but, sometimes HAL daemon didn't get a chance to handle data due to some processes take control of resources.
Increase event socket buffer from 2MB to 4MB
BUG: 191137443
Test: Device can connect to AP.
