tpm_tis: Fix IRQ autoprobing when using platform_device

The test was backwards, triggering IRQ autoprobing if the firmware
did not specify an IRQ, instead of triggering it only when the
module force parameter was specified.

Since autoprobing is not enabled on !x86 and the platform device is
currently only used on !x86, or with force, this has gone unnoticed.
