Make efx_process_channel() and falcon_process_eventq() return the
number of packets received rather than updating the quota, consistent
with new NAPI.
Since channels and RX queues are mapped one-to-one, remove return
value from falcon_handle_rx_event() and add a warning for events
with the wrong RX queue number.

Currently each channel can have at most one RX queue, so go straight to
that one.

We have long since given up doing RSS on Falcon A1 and therefore we
would always write the default value of 0.

efx_channel::has_interrupt is redundant with efx_channel::used_flags.
Remove efx_test_eventq() because it is now obviously unreachable.

gcc will automatically inline static functions with only one caller, and
may inline other functions depending on the kernel configuration and size
of the intermediate code.

Remove unmap_addr since it can be calculated from dma_addr, len and

Add efx_poll_loopback() function to test for successful completion of test.
Change efx_test_loopback() to end the test after 1 ms if
efx_poll_loopback() indicates success, and otherwise to wait for 100 ms
as before.
While we're here, rename efx_{rx,tx}_loopback() to
efx_{begin,end}_loopback() which more accurately reflect their
purpose.

Currently the board initialisation includes 2 delays of 1 second each.
Usually it is unnecessary to wait that long, so check before doing so.

efx_test_loopback() used "|" to combine the results of the RX and TX
phases. If both phases fail with different error codes, this results
in a bogus error code.
