ice: Add support to enable/disable all Rx queues before waiting
Currently when we enable/disable all Rx queues we do the following
sequence for each Rx queue and then move to the next queue.
1. Enable/Disable the Rx queue via register write.
2. Read the configuration register to determine if the Rx queue was
enabled/disabled successfully.
In some cases enabling/disabling queue 0 fails because of step 2 above.
Fix this by doing step 1 for all of the Rx queues and then step 2 for
all of the Rx queues.
Also, there are cases where we enable/disable a single queue (i.e.
SR-IOV and XDP) so add a new function that does step 1 and 2 above with
a read flush in between.
This change also required a single Rx queue to be enabled/disabled with
and without waiting for the change to propagate through hardware. Fix
this by adding a boolean wait flag to the necessary functions.
Also, add the keywords "one" and "all" to distinguish between
enabling/disabling a single Rx queue and all Rx queues respectively.
