ext4: fix symbolic enum printing in trace output
Trace's macro __print_flags() produce raw event's decraration w/o knowing actual
flags value
cat /sys/kernel/debug/tracing/events/ext4/ext4_ext_map_blocks_exit/format
..
__print_flags(REC->mflags, "", { (1 << BH_New),
For that reason we have to explicitly define it via special macro TRACE_DEFINE_ENUM()
Also add missed EXTENT_STATUS_REFERENCED flag.
