After last transmission, the device goes to sleep earlier
than the configured dynamic power save timeout. If timeout
is set to 400ms, device enters into sleep mode at around
330ms since from last TX.

This patch removes the msleep(1), which causes the delay
after ELP wakeup. Replaced with udelay(10), the variation
is around 7-10ms.

Change the driver to call ieee80211_beacon_loss function always when
BSS_LOST_EVENT is received. Reason for the change is that entering PSM
might fail before driver receives BSS_LOST_EVENT. In such case the
driver would disable PSM and the stack would not be notified about beacon
loss and connection loss detection would be delayed by tens of seconds.
