gsm322.c:arfcn2index patch

[Joshua Lackey]

(This is a patch against the latest, as of last night, git master.)

If you enable PCS, you'll never make it out of power-measurement without
this patch:
(This should be applied by everyone.)

If you enable PCS, you'll never receive packets without this patch: (which
I only include for e88 and e86 but it should work for others)
(This should be applied if you don't use DCS in your area.)
