wlan: Enhancing vosTraceEnable function.

vosTraceEnable API will now take two argument bitmask_of_moduleId
and enable. If bitmask_of_moduleId is set and enable is true,
MTRACE will be enabled for that corresponding bitmask. if enable
is false, MTRACE will be disabled for that module.
bitmask_of_moduleId=0 corresponds to all the modules.
