Chunwei Chen 061460dfe2 Fix get_zfs_sb race with concurrent umount 
Certain ioctl operations will call get_zfs_sb, which will holds an active
count on sb without checking whether it's active or not. This will result
in use-after-free. We fix this by using atomic_inc_not_zero to make sure
we got an active sb.
