be2net: perform temperature query in adapter regardless of its interface state
The be2net driver performs fw temperature queries on be_worker() routine, which is executed each second for each be_adapter. There is a frequency threshold to avoid fw query to happens at each call to be_worker(); instead, currently a fw query occurs once in 64 runs of the procedure. Nevertheless, this fw temperature query is invoked only for adapters which interface is up, so we can see I/O errors on read of hwmon counters from userspace (from tools like lm-sensors) in case we have adapters' functions which interface is down. This patch moves the fw query code to be invoked even if interface is down. No functional changes were introduced. Signed-off-by: Guilherme G.
