xfs: define fatal assert build time tunable
While configurable at runtime, the DEBUG mode assert failure behavior is usually either desired or not for a particular situation. For example, developers using kernel modules may prefer for fatal asserts to remain disabled across module reloads while QE engineers doing broad regression testing may prefer to have fatal asserts enabled on boot to facilitate data collection for bug reports. To provide a compromise/convenience for developers, create a Kconfig option that sets the default value of the DEBUG mode 'bug_on_assert' sysfs tunable. The default behavior remains to trigger kernel BUGs on assert failures to preserve existing behavior across kernel configuration updates with DEBUG mode enabled.
