avp_ops: failure to start if db ops used only in async mode

[ovidiusas]

If avp_db_query is used exclusively in async mode, during init, the avp_db_query function is not found in script and opensips is failing to start with the following error being reported:

ERROR:avpops:__fixup_db_query_avp: no db url defined to be used by this function

Workaround: define a dummy route where avp_db_query is used in sync mode.
The debug logs will show:

DBG:core:is_mod_func_used: function avp_db_query found to be used in script
DBG:core:find_mod_export: found <db_bind_api> in module db_mysql [/usr/local/lib64/opensips/modules/]

Hi, Ovidiu!

Are you using the async query in a switch statement? If so, this bug was already fixed in the master branch and I have just backported it to 2.1. A bit too late though :(.

Best regards,

All good now. Thanks for the backport.
