src and dst are only 8-bit-aligned, so accessing them as uint16_t causes
SIGBUS crashes on architectures like sparc.
This fixes ubsan runtime error: load of misaligned address for type
'const uint16_t', which requires 2 byte alignment

This can happen if s->ls changes from 0 to 1, but picture allocation is
skipped due to s->interlaced.
In that case ff_jpegls_decode_picture could be called even though the
s->picture_ptr frame has the wrong pixel format and thus a wrong
linesize, which results in a too small zero buffer being allocated.
This fixes an out-of-bounds read in ls_decode_line.
