brcmsmac: fix u16 overflow warning

DOT11_MIN_BEACON_PERIOD and DOT11_MAX_BEACON_PERIOD are
superfluous. The only invalid beacon period is 0. Comparing
a 16 bit quantity to 0xffff also causes a compile warning:

drivers/net/wireless/brcm80211/brcmsmac/main.c:5560 brcms_c_set_beacon_period()
 warn: impossible condition '(period > 65535) => (0-65535 > 65535)'

Observed from smatch analysis.
