Yunfei Dong 41671f0c01 media: mediatek: vcodec: adding lock to protect encoder context list 
[ Upstream commit afaaf3a0f6 ]

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.
