iavf: don't clear a lock we don't hold

iavf: don't clear a lock we don't hold

[ Upstream commit 2135a8d5c8186bc92901dc00f179ffd50e54c2ac ]

In iavf_configure_clsflower() the function will bail out if it is unable
to obtain the crit_section lock in a reasonable time. However, it will
clear the lock when exiting, so fix this.
