Yunjian Wang 4b10ae8027 bus/fslmc: fix VFIO group descriptor check 
The issue is that a file descriptor at 0 is a valid one. Currently
the file not found, the return value will be set to 0. As a result,
it is impossible to distinguish between a correct descriptor and a
failed return value. Fix it to return -ENOENT instead of 0.
