v4ldec: CB1 Fix NTX crash issue caused by a null pointer.. [1/1]

PD#SWPL-198070

Problem:
During the resolution switching process, `aml_buf_configure_update`
is invoked without assigning a value to `dynamic_mode`, which may
result in random values causing exceptions.

Solution:
`aml_buf_configure_update` needs to update the `dynamic_mode`
information promptly.
