a52dec: fix race in liba52dec lookup table initialization

a52_init initializes the IMDCT global state as well as creating
a new state. When two A52 decoders are created (eg, when two AC3
tracks are contained in a video), calls to a52_init may happen
at the same time, and the IMDCT initialization is not reentrant.
