Subject: [PATCH] wifi: ath11k: reduce the timeout value back for hw scan from 10 seconds to 1 second

For 11d scan, commit 9dcf6808b253 ("ath11k: add 11d scan offload support")
increased the timeout from one second to max 10 seconds when 11d scan
offload enabled and 6 GHz enabled, it is reasonable for the commit, it
is because the first 11d scan request is sent to firmware before the
first hw scan request after wlan load, then the hw scan started event
will reported from firmware after the 11d scan finished, it needs about
6 seconds when 6 GHz enabled, so increased it from one second to 10
seconds in the commit to avoid timed out for hw scan started. Then
another commit 1f682dc9fb37 ("ath11k: reduce the wait time of 11d scan
and hw scan while add interface") change the sequence of the first 11d
scan and hw scan, then ath11k will receive the hw scan started event
from firmware immediately for the first hw scan, thus ath11k does not
need set the timeout value to max 10 seconds again, and this is to set
the timeout value back from 10 seconds to 1 second.
