Log message:
Suppress low-level locking errors and warnings while using --sysinit.
Today, we use "suppress_messages" flag (set internally in init_locking fn based
on 'ignorelockingfailure() && getenv("LVM_SUPPRESS_LOCKING_FAILURE_MESSAGES")'.
This way, we can suppress high level messages like "File-based locking
initialisation failed" or "Internal cluster locking initialisation failed".
However, each locking has its own sequence of initialization steps and these
could log some errors as well. It's quite misleading for the user to see such
errors and warnings if the "--sysinit" is used (and so the ignorelockingfailure
&& LVM_SUPPRESS_LOCKING_FAILURE_MESSAGES environment variable). Errors and
warnings from these intermediary steps should be suppressed as well if requested.
This patch propagates the "suppress_messages" flag deeper into locking init
functions. I've also added these flags for other locking types for consistency,
though it's not actually used for no_locking and readonly_locking.
