xfs: factor out nodiscard helpers
The changes to skip discards of speculative preallocation and unwritten extents introduced several new wrapper functions through the bunmapi -> extent free codepath to reduce churn in all of the associated callers. In several cases, these wrappers simply toggle a single flag to skip or not skip discards for the resulting blocks. The explicit _nodiscard() wrappers for such an isolated set of callers is a bit overkill. Kill off these wrappers and replace with the calls to the underlying functions in the contexts that need to control discard behavior. Retain the wrappers that preserve the original calling conventions to serve the original purpose of reducing code churn. This is a refactoring patch and does not change behavior.
