Subject: [PATCH] staging: wilc1000: restore wilc_spi_dev variable

A recent change to wilc1000 accidentally deleted an important
variable, so we now get a build error when the SPI mode is
selected:

ERROR: "wilc_spi_dev" [drivers/staging/wilc1000/wilc1000.ko] undefined!

This partially reverts the broken commit to put the variable back.
