ath9k: simplify ATH_EP_RND
Remove the embedded branch to make the ATH_EP_RND macro a little
clearer. The new version also generates better code, saving 24
bytes of text:
text data bss dec hex filename
87858 1641 24 89523 15db3 ath9k_orig.ko
87834 1641 24 89499 15d9b ath9k_new.ko
Although neither version handles negative values particularly well,
the lone caller clamps all negative values to zero anyway. I have
verified that the results are the same for the range of possible
positive rssi values.
