[Asterisk-code-review] core_unreal: Fix deadlock with T.38 control frames. (asterisk[16])

[Joshua Colp]

Hello George Joseph, Friendly Automation, 

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

    https://gerrit.asterisk.org/c/asterisk/+/15651

to look at the new patch set (#3).

Change subject: core_unreal: Fix deadlock with T.38 control frames.
......................................................................

core_unreal: Fix deadlock with T.38 control frames.

When using the ast_unreal_lock_all function no channel
locks can be held before calling it.

This change unlocks the channel that indicate was
called on before doing so and then relocks it afterwards.

ASTERISK-29035
