tpm: Fix a possible dereference of ERR_PTR in tpm_init()
Smatch reports:
drivers/char/tpm/tpm-interface.c:470 tpm_init() error:
'tpm_class' dereferencing possible ERR_PTR()
If class_create() returns error pointer, we are dereferencing a possible
error pointer. Fix this by moving the dereference post error handling.
Fixes: a010eb881243 ("tpm: fix up the tpm_class shutdown_pre pointer when created")
