nl80211: Fix beacon rate configuration for legacy rates 36, 48, 54 Mbps

Browse source 
Typecasting takes precedence over division here, so the legacy rates
larger than 255 * 100 kbps (i.e., 36, 48, 54 Mbps) ended up getting
truncated to invalid values.

Fix this by typecasting the value after the division.
