enb,rrc: fix bearer re-activation after max KO
...
this patch makes sure that if RBs have been deactivated after
max KO on either the DL or the UL, they are reactivated if either
of them is working again.
UL/DL are always activated together, even if just one of them
recovers. The KO counter (or timer), however, is not stopped implicitly.

simplification of multiqueue design.
...
- the consumer does multi-staged waiting:
1. spins first across all queues in a RR fashion
2. each queue access is done with a try_lock.
3. if the try_lock fails, it increases the number of spins needed
2. if no queue had data, the consumer sleeps for 100 usec.
- no differentiation between queues, in terms of notification features

this patch splits the counter and timer handling for PHY DL, PHY UL,

does not cancel the UL RLF timer, and vice versa.
They all use the same timeout value which is user-configurable.
