[LTP] [PATCH v3] syscalls/preadv2/preadv203: set mount_device flag

[Murphy Zhou]

Now the tests are running in MOUNTPOINT without it mounted. Fails on
NFS, cifs, tmpfs:

    preadv203.c does not set mount_device, which makes BROK:
      preadv203.c:122: BROK: preadv2() failed: EOPNOTSUPP

v3:
  improve commit message
v2:
  set mount_device in preadv203.c, rather than in the library
