tpm: avoid -Wunused-but-set-variable

Browse source

commit 6f1d4d2ecf upstream.

Outside of the EFI tpm code, the TPM_MEMREMAP()/TPM_MEMUNMAP functions are
defined as trivial macros, leading to the mapping_size variable ending
up unused:

In file included from drivers/char/tpm/tpm-sysfs.c:16:
In file included from drivers/char/tpm/tpm.h:28:
include/linux/tpm_eventlog.h:167:6: error: variable 'mapping_size' set but not used [-Werror,-Wunused-but-set-variable]
  167 |         int mapping_size;

Turn the stubs into inline functions to avoid this warning.
