Prevent crash when trying to serialize packet with missing encryption key

b/151452116 shows GFE crashing in QuicFramer due to dereferencing a null pointer. This CL adds checks for this and triggers a QUIC_BUG instead of crashing. Our goal is to have the issue reproduce with the QUIC_BUG so we can investigate further what's causing us to get into that state.

gfe-relnote: replace crash with GFE_BUG, not flag-protected
