Revert "mei: vsc: Call wake_up() in the threaded IRQ handler"

This reverts commit 058a38acba15fd8e7b262ec6e17c4204cb15f984.

It's not necessary to avoid a spinlock, a sleeping lock on PREEMPT_RT, in
an interrupt handler as the interrupt handler itself would be called in a
process context if PREEMPT_RT is enabled. So revert the patch.
