avcodec/jpeglsdec: Don't presume the context to contain a JLSState
Before 9b3c46a081a9f01559082bf7a154fc6be1e06c18 every call to ff_jpegls_decode_picture() allocated and freed a JLSState. This commit instead put said structure into the context of the JPEG-LS decoder to avoid said allocation. But said function can also be called from other MJPEG-based decoders and their contexts doesn't contain said structure, leading to segfaults. This commit fixes this: The JLSState is now allocated on the first call to ff_jpegls_decode_picture() and stored in the context.
