[complexity] missing pop_wmops() in vbap_init_data()

Basic info

• Present with df307502 (tested on macOS)

Bug description

Missing pop_wmops() can cause unbalanced push/pop calls leading to the following error:

update_wmops(): WMOPS caller stack corrupted - check that all push_wmops() are matched with pop_wmops()!

The cause seems to be a missing pop_wmops() in vbap_init_data(): https://forge.3gpp.org/rep/sa4/audio/ivas-basop/-/blob/main/lib_rend/ivas_vbap.c#L470

This is present in the inactive float code lower down: https://forge.3gpp.org/rep/sa4/audio/ivas-basop/-/blob/main/lib_rend/ivas_vbap.c#L719
