tpm/tpm_ftpm_tee: Fix error handling in ftpm_mod_init()

Browse source

[ Upstream commit 2b7d07f7ac ]

The ftpm_mod_init() returns the driver_register() directly without checking
its return value, if driver_register() failed, the ftpm_tee_plat_driver is
not unregistered.

Fix by unregister ftpm_tee_plat_driver when driver_register() failed.
