media: mediatek: vcodec: adding lock to protect encoder context list
[ Upstream commit afaaf3a0f647a24a7bf6a2145d8ade37baaf75ad ]
Add a lock for the ctx_list, to avoid accessing a NULL pointer
within the 'vpu_enc_ipi_handler' function when the ctx_list has
been deleted due to an unexpected behavior on the SCP IP block.
