[PATCH v2 1/7][next] printk: ringbuffer: rename DESC_COMMITTED_MASK flag

[John Ogness]

The flag DESC_COMMITTED_MASK has a much longer name compared to the
other state flags and also is in past tense form, rather than in
command form. Rename the flag to DESC_COMMIT_MASK in order to match
the other state flags.
