Subject: tpm_tis: Use devm_free_irq not free_irq

From: Jason Gunthorpe <jgunthorpe@obsidianresearch.com>

commit 727f28b8ca24a581c7bd868326b8cea1058c720a upstream.

The interrupt is always allocated with devm_request_irq so it
must always be freed with devm_free_irq.

Fixes: 448e9c55c12d ("tpm_tis: verify interrupt during init")
