ocfs2: annotate more flexible array members with __counted_by_le()

Annotate flexible array members of 'struct ocfs2_local_alloc' and 'struct
ocfs2_inline_data' with '__counted_by_le()' attribute to improve array
bounds checking when CONFIG_UBSAN_BOUNDS is enabled, and prefer the
convenient 'memset()' over an explicit loop to simplify
'ocfs2_clear_local_alloc()'.
