mountd: fix mount issue due to comparison with uninitialized uuid

Fix mount issue due to comparison of uninitialized variable
u(uuid) with parsed->fhuuid when uuid_by_path return 0.

/tmp/usb
192.168.1.0/16(ro,no_root_squash,no_subtree_check,fsid=0)
/tmp/usb/sda1       192.168.1.0/16(ro,no_root_squash,no_subtree_check)
/tmp/usb/sdb1       192.168.1.0/16(ro,no_root_squash,no_subtree_check)

mount -t nfs -o nolock,nfsvers=3 192.168.1.2:/tmp/usb/sda1 /tmp/sda1
mount -t nfs -o nolock,nfsvers=3 192.168.1.2:/tmp/usb/sdb1 /tmp/sdb1

results in below mountd error:
mountd: /tmp/usb and /tmp/usb/sdb1 have same filehandle for
192.168.1.0/16, using first

when uuid_by_path returned 0, by chance, garbage value of u was same as
parsed->fhuuid(of sdb1), and comparison of these resulted in above
error.
