xfs: check healthmon outbuffer space correctly

LOLLM notices that the outbuf space check in xfs_healthmon_format_pop
isn't quite correct -- it checks that there's enough space to write a
xfs_healthmon_event object, but the outbuffer is supposed to contain
xfs_health_monitor_event objects.  Fix this by adding a helper, and
refactoring all three outbuf size checks to use it.
