[Asterisk-code-review] pbx.c: On error, ast_add_extension2_lockopt should always free 'data' (asterisk[13])

[Sean Bright]

Hello Joshua Colp, Friendly Automation, 

I'd like you to reexamine a change. Please visit

    https://gerrit.asterisk.org/c/asterisk/+/15021

to look at the new patch set (#2).

Change subject: pbx.c: On error, ast_add_extension2_lockopt should always free 'data'
......................................................................

pbx.c: On error, ast_add_extension2_lockopt should always free 'data'

In the event that the desired extension already exists,
ast_add_extension2_lockopt() will free the 'data' it is passed before
returning an error, so we should not be freeing it ourselves.

Additionally, there were two places where ast_add_extension2_lockopt()
could return an error without also freeing the 'data' pointer, so we
add that.
