Arnd Bergmann 0e7facea6d wifi: iwlegacy: work around excessive stack usage on clang/kasan

In some rare randconfig builds, I seem to trigger a bug in clang where
it unrolls a loop but then runs out of registers, which then get
spilled to the stack:

net/wireless/intel/iwlegacy/4965-rs.c:2262:1: error: stack frame size (1696) exceeds limit (1280) in 'il4965_rs_rate_init' [-Werror,-Wframe-larger-than]

This seems to be the same one I saw in the omapdrm driver, and there is
an easy workaround by not inlining the il4965_rs_rate_scale_clear_win
function.
