drivers/net/wireless/atmel.c: Use time_* macros

The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values.

So following patch implements usage of the time_after() macro, defined at linux/jiffies.h, which deals with wrapping correctly
