wlan: Use system time instead of jiffies for BSS received time

During late suspend jiffies will not be incremented. Because of this
scan results are not age out as the delta of current time and the BSS
received time is not correct.

To address this, use the system time instead of jiffies for the
BSS received time and also make sure to use system time in all
other functions.
