scsi: qla2xxx: Use 64-bit FPM word counters for 29xx host stats

Browse Source 
29xx provides the 64-bit FPM transmit/receive word counters in the link
statistics block, like 83xx/27xx/28xx.  qla2x00_get_fc_host_stats() only
consumed those counters for the older families and fell back to the
software approximation (input/output bytes >> 2) on 29xx, reporting less
accurate rx_words/tx_words.

Add IS_QLA29XX() to the high-speed branch so 29xx reports the hardware
word counters.
