iwlwifi: rename functions in transport layer
1) s/tx_queue/txq
for the sake of consistency.
2) s/rx_queue/rxq
for the sake of consistency.
3) Make all functions begin with iwl_pcie_
iwl_queue_init and iwl_queue_space are an exception
since they are not PCIE specific although they are in
pcie subdir.
4) s/trans_pcie_get_cmd_string/get_cmd_string
it is much shorter and used in debug prints which
are long lines.
5) s/iwl_bg_rx_replenish/iwl_pcie_rx_replenish_work
this better emphasizes that it is a work
6) remove invalid kernelDOC markers
pcie/tx.c and pcie/trans.c still needs to be cleaned up.
