[PATCH v3] wifi: mwifiex: Convert to use jiffies macro

[Chen Yufan]

Use time_after macro instead of using
jiffies directly to handle wraparound.
The modifications made compared to the previous version are as follows:
1. change the type of mwifiex_auto_tdls_peer::rssi_jiffies to
unsigned long.

The patch changelog should not be part of the commit message, you should have it afterwards.
