ice: Fix bugs in control queue processing
This patch is a consolidation of multiple bug fixes for control queue
processing.
1) In ice_clean_adminq_subtask() remove unnecessary reads/writes to
registers. The bits PFINT_FW_CTL, PFINT_MBX_CTL and PFINT_SB_CTL
are not set when an interrupt arrives, which means that clearing them
again can be omitted.
2) Get an accurate value in "pending" by re-reading the control queue
head register from the hardware.
3) Fix a corner case involving lost control queue messages by checking
for new control messages (using ice_ctrlq_pending) before exiting the
cleanup routine.
