cxgb4: Allocate Tx queues dynamically

Browse Source 
Allocate resources dynamically for Upper layer driver's (ULD) like
cxgbit, iw_cxgb4, cxgb4i and chcr. The resources allocated include Tx
queues which are allocated when ULD register with cxgb4 driver and freed
while un-registering. The Tx queues which are shared by ULD shall be
allocated by first registering driver and un-allocated by last
unregistering driver.
