swapon01 from ubuntu_ltp_syscalls failed with TBROK Test killed on ext2

[Po-Hsu Lin]

This is a new failure after upstream has enabled the test on all filesystems (a0fb0c3f24 "swapon01: Test on all filesystems")

Test failed with timeout, however set a timeout multiplier does not help.

It looks like the swapon will succeed:
