Rob Norris 391e85f519 ZIL: add zil_commit_flags() to make honouring failmode= optional
The vast majority of calls to zil_commit() follow VFS ops, and should
honour the failmode= setting - either wait for sync, or return error.
Some calls however are part of a larger syncing op, and shouldn't ever
block if something goes wrong.

To allow this, we introduce zil_commit_flags(), with a flag
ZIL_COMMIT_FAILMODE to indicate whether or not the pool failmode should
be honoured. zil_commit() is now a wrapper that always sets this flag,
but any caller wanting a different behaviour can request ZIL_COMMIT_NOW
instead to have the call return failure if the pool suspends, regardless
of the failmode= setting.
