-vpx_codec_enc_init_multi: fix double free on init failure
-
-In `vp8e_init()`, the encoder would take ownership of
-`mr_cfg.mr_low_res_mode_info` even if `vp8_create_compressor()` failed.
-This caused confusion at the call site as other failures in
-`vp8e_init()` did not result in ownership transfer and the caller would
-free the memory. In the case of `vp8_create_compressor()` failure both
-the caller and `vpx_codec_destroy()` would free the memory, causing a
-crash. `mr_*` related variables are now cleared on failure to prevent
-this situation.
