gbproxy: Check tlli_info when patching, fix APN patching
Currently the numeric TLLI or tlli_info's enable_patching flag is used to decide, whether a APN shall be patched or the secondary SGSN shall be used. Using the numeric TLLI imposes a problem, when TLLI/P-TMSI patching is used, since gbproxy_check_tlli uses the BSS side TLLI namespace when trying to get the tlli_info. This patch modifies the gbproxy_check_tlli() function to accept a tlli_info pointer instead of a numeric TLLI. The tlli_info is already available when the function is called. Since this a similar approach has been used by accessing the enable_patching flag directly, this commit unifies checking by always using this function instead of the flag outside of gb_proxy_tlli.c. This fixes the APN patching that doesn't work currently when P-TMSI patching is enabled. Sponsored-by: On-Waves ehf
