x86/tmp.c: handle failure to allocate log entry
73336f6 
`out_digest` is used during hashing above and thus can't be NULL in
tpm_hash_extend12().  Use a throw-away buffer for the computed hash.

x86/tpm.c: wait until TPM is ready to accept a new command
ad99695 
Not doing this caused an infinite loop waiting for a response after
sending STS_TPM_GO when TPM wasn't expecting any input and probably just
ignored it.
