nicintel_spi.c: Cache FLA register value

Only read the FLA register to get the state of MISO, and when requesting
and releasing the bus. This is an optimisation to speed things up.

Tested on a 8086:1533 (i210 GbE), reads still return the same data.
This cuts the time to read a Winbond W25Q80.V (1 MiB, SPI) from 48
seconds down to 33 seconds, i.e. a 45% increase in speed.
