S2io: Fixes to enable multiple transmit fifo support
Fixes to enable multiple transmit fifos (upto a maximum of eight).
- Moved single tx_lock from struct s2io_nic to struct fifo_info.
- Moved single ufo_in_band_v structure from struct s2io_nic to struct
fifo_info.
- Assign the respective interrupt number for the transmitting fifo in the
transmit descriptor (TXD).
- Added boundary checks for number of FIFOs enabled and FIFO length.
