avcodec/v4l2_m2m_dec: Fix decoding on Odroid XU4

c0c79461967 unintentianally changed the initialization flow of the
decoder: It caused the capture buffers to be initialized on
v4l2_m2m.c:180 in v4l2_configure_contexts(). This breaks h264 decoding
on the Odroid XU4 (RPI4 was not affected).

This commit postpones capture buffer initialization
as before c0c79461967 to fix the issue.
