Colin Ian King 31c9a4b24d KEYS: trusted: Fix memory leak on object td 
commit 83a775d5f9bfda95b1c295f95a3a041a40c7f321 upstream.

Two error return paths are neglecting to free allocated object td,
causing a memory leak. Fix this by returning via the error return
path that securely kfree's td.

Fixes clang scan-build warning:
security/keys/trusted-keys/trusted_tpm1.c:496:10: warning: Potential
memory leak [unix.Malloc]
