integrity: Fix __integrity_init_keyring() section mismatch

Browse source 
With gcc-4.6.3:

    WARNING: vmlinux.o(.text.unlikely+0x24c64): Section mismatch in reference from the function __integrity_init_keyring() to the function .init.text:set_platform_trusted_keys()
    The function __integrity_init_keyring() references
    the function __init set_platform_trusted_keys().
    This is often because __integrity_init_keyring lacks a __init
    annotation or the annotation of set_platform_trusted_keys is wrong.

Indeed, if the compiler decides not to inline __integrity_init_keyring(),
a warning is issued.

Fix this by adding the missing __init annotation.

Fixes: 9dc92c4517 ("integrity: Define a trusted platform keyring")
