ASN.1: mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: lib/asn1_decoder.c:386:6: warning: this statement may fall through [-Wimplicit-fallthrough=] lib/asn1_decoder.c:449:6: warning: this statement may fall through [-Wimplicit-fallthrough=] Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enabling -Wimplicit-fallthrough.
