qcacmn: Fix truncation issues due to typecast in QDF time APIs

Currently there is an issue wrt truncation in the __qdf_system_time_after()
& __qdf_system_time_after_eq() QDF APIs where the input system ticks
(jiffies) which are of type unsigned long are getting truncated due to
typecast to long before comparison. Due to this typecasting, there is
likelihood of a wrong comparison resulting in wrong actions being
taken in the caller.

Typecast the result of the comparison instead to fix this problem.
