If DEBUG_SECTION_MISMATCH enabled, __calc_tpm2_event_size() will not be inlined, this cause section mismatch like this:

WARNING: modpost: vmlinux.o(.text.unlikely+0xe30c): Section mismatch in reference from the variable L0 to the function .init.text:early_ioremap() The function L0() references the function __init early_memremap(). This is often because L0 lacks a __init annotation or the annotation of early_ioremap is wrong.

Fix it by using __always_inline instead of inline for the called-once function __calc_tpm2_event_size().
