[LTP] [PATCH] zram01: Specify filesystem type explicitly in mount

[Avinesh Kumar]

util-linux 2.42 converts "ntfs" to "ntfs3" during auto-detection,
causing mount failures on systems with CONFIG_NTFS3_FS disabled
even when ntfs-3g is available.

tst_supported_fs_types.c:141: TINFO: FUSE does support ntfs
tst_supported_fs_types.c:67: TINFO: mkfs.ntfs does exist
tst_supported_fs_types.c:137: TINFO: Filesystem ntfs3 is not supported
...
...
zram01 6 TINFO: mount /dev/zram7
mount: /tmp/LTP_zram01.YG3YHQhMER/zram7: unknown filesystem type 'ntfs3'.
       dmesg(1) may have more information after failed mount system call.
zram01 6 TBROK: mount /dev/zram7 zram7 failed

Fix by specifying -t option with the filesystem type that LTP
verified as supported, avoiding auto-detection.
