Michael Niedermayer 82b7a19f4a avcodec/hevc: keep the active VPS when a layer SPS is cleared ...

set_sps(s, l, NULL) drops the SPS of a non-base layer whose VPS does not
match the active one. It also dropped the active VPS of the base layer,
the next base layer frame then dereferenced the NULL VPS in
ff_hevc_is_alpha_video().

Fixes: NULL pointer dereference

Regression since: c7f0753a6b
Found during the review of https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/24895
