Fix incorrect error code in equeue

[kalaposfos13]

According to the system library, the out parameter being null should not warrant returning an error code. This fixes LBP3's input handling (and probably games with a similar issue), as it was stuck in a loop due to it thinking the function timed out because of this.

Unsurprisingly, this breaks The Last of Us Remastered. The game uses equeues to check for trophies, using a while loop that loops until sceKernelWaitEqueue returns an error.
I think you should take a closer look at the current implementation for this function, as it seems like you've misunderstood the purpose of that ETIMEDOUT return. It's there to properly handle cases where no events are triggered during the wait.
