pds_core: Fix FW recovery detection

Commit 523847df ("pds_core: add devcmd device interfaces") included
initial support for FW recovery detection. Unfortunately, the ordering
in pdsc_is_fw_good() was incorrect, which was causing FW recovery to be
undetected by the driver. Fix this by making sure to update the cached
fw_status by calling pdsc_is_fw_running() before setting the local FW
gen.
