Subject: [PATCH] tpm2: replace _cleanup_tpm2_* macros with _cleanup_()
Remove _cleanup_tpm2_context_ and _cleanup_tpm2_handle_ macros, replacing their
use with _cleanup_(tpm2_context_unrefp) and _cleanup_(tpm2_handle_freep),
respectively.
(cherry picked from commit 1dc8f51841f2a552da8924c4d5501c7b1c757ba8)
