printk: Rename console_replay_all() and update context

Browse Source 
Rename console_replay_all() to console_try_replay_all() to make
clear that the implementation is best effort. Also, the function
should not be called in NMI context as it takes locks, so update
the comment in code.

Fixes: 693f75b91a ("printk: Add function to replay kernel log on consoles")
Fixes: 1b743485e2 ("tty/sysrq: Replay kernel log messages on consoles via sysrq")
