[PATCH][TRIVIAL] if_spi: Fix compilation warning - unused variable

[Nikanth Karthikesan]

if_spi: Fix compilation warning - unused variable 'spi'

drivers/net/wireless/libertas/if_spi.c: In function ‘if_spi_init_card’:
drivers/net/wireless/libertas/if_spi.c:1035: warning: unused variable ‘spi’

The variable is used only in a macro which uses the args only for DEBUG builds.
Remove the 'spi' variable completely.
