Subject: [PATCH] tpm,tpm_tis: Avoid warning splat at shutdown
If interrupts are not activated the work struct 'free_irq_work' is not
initialized. This results in a warning splat at module shutdown.
Fix this by always initializing the work regardless of whether interrupts
are activated or not.

Fixes: 481c2d14627d ("tpm,tpm_tis: Disable interrupts after 1000 unhandled IRQs")
