Previously, the dell_idrac_fans check crashed with KeyError: '' when an iDRAC reported an empty string (or any other value outside the documented range 1..10) in the fan-status column, sending the affected fan service to UNKNOWN with a stack trace.

The check now reports such fans as UNKNOWN and continues instead of crashing, and discovery ignores fans whose status is not one of the documented values, in the same way it already ignores fans reported as OTHER or UNKNOWN.
