x86/mce: Remove mce_inject_log() in favor of mce_log()
The mutex in mce_inject_log() became unnecessary with commit5de97c9f6d
("x86/mce: Factor out and deprecate the /dev/mcelog driver"), though the original reason for its presence only vanished with commit7298f08ea8
("x86/mcelog: Get rid of RCU remnants"). Drop the mutex. And as that makes mce_inject_log() identical to mce_log(), get rid of the former in favor of the latter. Signed-off-by: Jan H.
