of: kexec: Mark ima_{free,stable}_kexec_buffer() as __init
This commit has no direct upstream equivalent.
After commit d48016d74836 ("mm,ima,kexec,of: use memblock_free_late from
ima_free_kexec_buffer") in 5.15, there is a modpost warning for certain
configurations:
WARNING: modpost: vmlinux.o(.text+0xb14064): Section mismatch in reference from the function ima_free_kexec_buffer() to the function .init.text:__memblock_free_late()
The function ima_free_kexec_buffer() references
the function __init __memblock_free_late().
This is often because ima_free_kexec_buffer lacks a __init
annotation or the annotation of __memblock_free_late is wrong.
In mainline, there is no issue because ima_free_kexec_buffer() is marked
as __init, which was done as part of commit b69a2afd5afc ("x86/kexec:
Carry forward IMA measurement log on kexec") in 6.0, which is not
suitable for stable.
Mark ima_free_kexec_buffer() and its single caller
ima_load_kexec_buffer() as __init in 5.15, as ima_load_kexec_buffer() is
only called from ima_init(), which is __init, clearing up the warning.
