libavcodec/jpeg2000.c: Precinct size check removed
This patch removes a check which throws an error if
the log2 precinct width/height is 0. The standard allows
the first component to have 0 as the log2 width/height.
However, to ensure proper intialization of coding style,
an extra check has been added.
