mwifiex: Use to_delayed_work() 

Author: Amitoj Kaur Chawla <amitoj1606@gmail.com>

Introduce the use of to_delayed_work() helper function instead of open
coding it with container_of()

A simplified version of the Coccinelle semantic patch used to make
this change is:

//
@@
expression a;
symbol work;
@@
- container_of(a, struct delayed_work, work)
+ to_delayed_work(a)
//
