Added gc_reclaimed_segments and gc_segment_mode sysfs nodes.
1) "gc_reclaimed_segments" shows how many segments have been
reclaimed by GC during a specific GC mode.
2) "gc_segment_mode" is used to control for which gc mode
the "gc_reclaimed_segments" node shows.

As 5kft reported in [1]:
set_compress_context() should set compress level into .i_compress_flag
for zstd as well as lz4hc, otherwise, zstd compressor will still use
default zstd compress level during compression, fix it.
