bssgp_fc_test: sanitizer: free msgb context when done
Print remaining msgbs when done, then free the entire tall_msgb_context. To be
able to do that, call msgb_talloc_ctx_init() and use its return value.
A subsequent patch will fix a known mem leak and add assertions for 0b in 1
blocks remaining in the tall_msgb_context.
Helps fix sanitizer build on debian 9.
