imx-vpu: fix checks of IOGetVirtMem() return value
The IOGetVirtMem() routine returns the address of a memory block
or -1 (MAP_FAILED) to indicate an error.
Many callers of this routine tested the return value for <= 0
to detect failure, and at least with a 3G/1G memory split
configured in the kernel, a negative number (!= -1) is a
valid (successful) return value.
Without this patch, the IOSystemInit() will often detect
failure incorrectly.
