ice: don't busy wait for Rx queue disable in ice_qp_dis()

When ice driver is spammed with multiple xdpsock instances and flow
control is enabled, there are cases when Rx queue gets stuck and unable
to reflect the disable state in QRX_CTRL register. Similar issue has
previously been addressed in commit 13a6233b ("ice: Add support to
enable/disable all Rx queues before waiting").

To workaround this, let us simply not wait for a disabled state as later
patch will make sure that regardless of the encountered error in the
process of disabling a queue pair, the Rx queue will be enabled.
