ath9k_hw: Fix possible OOB array indexing in gen_timer_index[] on 64-bit
commit c90017dd43f0cdb42134b9229761e8be02bcd524 upstream.
debruijn32 (0x077CB531) is used to index gen_timer_index[]
which is an array of 32 u32. Having debruijn32 as unsigned
long on a 64-bit platform will result in indexing more than 32
in gen_timer_index[] and there by causing a crash. Make it
unsigned to fix this issue.
