Subject: [PATCH] rtl8xxxu: remove the unused variable timeout value assignment

From: Kaixu Xia <[email protected]>

The value of variable timeout is overwritten by the following statement in
rtl8xxxu_gen1_init_aggregation(), so here the value assignment is useless.
Remove it.

Sorry this is the wrong way to do this. If the if statement is no longer
needed, then remove it, don't just make it do nothing.

Nack
