restrict init task to fw and tps updates - launching only conditionally as needed
- Remove remaining calls to ADAPTER_LOCK by moving the two
  remaining globally serialized operations (toe initialization and
  firmware install) to a dedicated adapter task
- change ifdi_rx_intr_enable to take a 16 bit queue id
- change vaddrs in iflib_qset_addr_get to caddr_t
- add "friend" functions to give access to iflib's sctx and qset
  mutexes so that drivers with special needs (e.g. cxgb which supports
  upper level protocols) can synchronize with iflib
reflect small interface changes in the last iflib commit
Fixes to make iflib converted cxgb compile
(albeit leaving some glaring omissions)
