FIXED: "Trying to vfree() nonexistent vm area..." messages in sound driver(s).

The cause of the messages is that parts of the sound_mem_blocks array are
vfree'd in opl3.c and uart401.c. The messages come when the whole array is
vfree'd in soundcard.c (line 464.) This patch solves the problem in a way
consistent with the rest of the sound driver(s).
