wmmemload: call usleep() directly in main loop

Browse source 
The reason is the same as in the analogous patch for wmwifi
in commit 1e34ea7f980; it improves considerably the efficiency.

Keeping the 'interval' unchanged (set to 1 sec), with this change
the number of wakeups as measured by powertop goes from around 14 wakeups/sec
to around 2 wakeup/sec.
