tpm_crb: check for bad response size
commit 8569defde8057258835c51ce01a33de82e14b148 upstream.
Make sure size of response buffer is at least 6 bytes, or
we will underflow and pass large size_t to memcpy_fromio().
This was encountered while testing earlier version of
locality patchset.
Fixes: 30fc8d138e912 ("tpm: TPM 2.0 CRB Interface")
