xfs: convert log tail checking to a warning
On the Power platform, the log tail debug checks fire excessively causing the system to panic early in testing. The debug checks are known to be racy, though on x86_64 there is no evidence that they trigger at all. We want to keep the checks active on debug systems to alert us to problems with log space accounting, but we need to reduce the impact of a racy check on testing on the Power platform. As a result, convert the ASSERT conditions to warnings, and allow them to fire only once per filesystem mount. This will prevent false positives from interfering with testing, whilst still providing us with the indication that they may be a problem with log space accounting should that occur.
