bnx2: Put tx ring variables in a separate struct.
In preparation for multi-ring support, tx ring variables are now put
in a separate bnx2_tx_ring_info struct. Multi tx ring will not be
enabled until it is fully supported by the stack. Only 1 tx ring
will be used at the moment.
The functions to allocate/free tx memory and to initialize tx rings
are now modified to handle multiple rings.
