  hw/audio/fmopl: fix segmentation fault

Current code allocates the memory for ENV_CURVE too late. Move
allocation to OPLOpenTable() and deallocation to OPLCloseTable().

To reproduce the bug start qemu with -soundhw adlib.

Fixes 2eea51bd01 "hw/audio/fmopl: Move ENV_CURVE to .heap to save
32KiB of .bss"
