tpm xen: Remove bogus tpm_chip_unregister

Browse source 
commit 1f0f30e404b3d8f4597a2d9b77fba55452f8fd0e upstream.

tpm_chip_unregister can only be called after tpm_chip_register.
devm manages the allocation so no unwind is needed here.

Fixes: afb5abc262 ("tpm: two-phase chip management functions")
