wifi: mwifiex: decrease timeout waiting for host sleep from 10s to 5s

In commit 52250cbee7f6 ("mwifiex: use timeout variant for
wait_event_interruptible") it was noted that sometimes we seemed
to miss the signal that our host sleep settings took effect. A
10 second timeout was added to the code to make sure we didn't
hang forever waiting. It appears that this problem still exists
and we hit the timeout sometimes for Chromebooks in the field.

Recently on ChromeOS we've started setting the DPM watchdog
to trip if full system suspend takes over 10 seconds. Given
the timeout in the original patch, obviously we're hitting
the DPM watchdog before mwifiex gets a chance to timeout.

While we could increase the DPM watchdog in ChromeOS to avoid
this problem, it's probably better to simply decrease the
timeout. Any time we're waiting several seconds for the
firmware to respond it's likely that the firmware won't ever
respond. With that in mind, decrease the timeout in mwifiex
from 10 seconds to 5 seconds.
