wifi: rt2x00: remove redundant check if u8 array element is less than zero

Browse Source 
The check on vga_gain[ch_idx] being less than zero is always false since
vga_gain is a u8 array. Clean up the code by removing the check and the
following assignment. Cleans up clang scan build warning:

drivers/net/wireless/ralink/rt2x00/rt2800lib.c:9704:26: warning:
result of comparison of unsigned expression < 0 is always
false [-Wtautological-unsigned-zero-compare]
