[PATCH 4/4] qmi: voicecall: Remove redundant initialization to NULL

[Denis Kenzior <denkenz@gmail.com>]

param was needlelly initialized to NULL in answer() and
release_specific().  Since all error paths free both cbd and param,
declare & initialize these variables at the start of the function.

Handle dial() similarly for consistency.
