[PATCH] net/wireless/atmel: fix defined but not used warning

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

Fix a build warning in drivers/net/wireless/atmel/ when CONFIG_PROC_FS
is not enabled by marking the unused function as __maybe_unused.

../drivers/net/wireless/atmel/atmel.c:1402:12: warning: 'atmel_proc_show' defined but not used [-Wunused-function]
