[PATCH] spi: spi-amd: remove unused variable 'opcode'

[Zheng Bin <zhengbin13@xxxxxxxxxx>]

Fixes gcc '-Wunused-variable' warning:

drivers/spi/spi-amd.c:171:17: warning: unused variable ‘opcode’ [-Wunused-variable]

It is introduced by commit bbb336f39efc ("spi: spi-amd:
Add AMD SPI controller driver support"), but never used,
so remove it.
