[0/2] xfs: Clear a couple of W=1 warnings

Message

For configs XFS_DEBUG and XFS_WARN disabled, there are a couple of W=1
warnings for unused variables. I have attempted to clear these here by
simply marking the unused variables as __maybe_unused.

I suppose that another solution would be to change the ASSERT() statement
relevant to this config from:
#define ASSERT(expr) ((void)0)
to:
#define ASSERT(expr) ((void)(expr))

Then the problem is that some local variables need to lose the
#ifdef XFS_DEBUG guards, as those variables are now referenced in
ASSERT(). This means that the objcode grows ever so slightly. I
assume that this has all been considered previously...

Based on v6.9-rc5
