Subject: [PATCH] avcodec/bsf/eac3_core: clear profile value on init()

The output stream no longer has Atmos metadata, so the
AV_PROFILE_EAC3_DDP_ATMOS profile, if it was set, is no longer valid.

Signed-off-by: James Almer <jamrial@gmail.com>
(cherry picked from commit c77c0e580a39580c085b7182885601015b7f3da4)
