mm: Fix reliable_debug in proc not consistent with boot parameter problem

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4SK3S
CVE: NA

--------------------------------

Now reliable_debug will be consistent with boot parameter. If
reliable_debug in boot parameter is set t "F", reliable_debug in proc will
be 13 which means only fallback is closed.
