[LTP] [PATCH] madvise06: Do no set swap limit

[Richard Palethorpe]

Setting the swap limit is unnecessary for this test. By default it
appears to be set to some large value which is OK. Setting it may fail
for reasons unrelated to the test's purpose making the test less
reliable.

I should not have included this in the first update to the test. It
appears that it fails with EACCES on at least one configuration, where
the test ran previously. Also it could fail with EBUSY in theory.

I don't know why limit_in_bytes can be set, but memsw.limit_in_bytes
results in EACCES. This is interesting, however should be the focus of
a different test IMO.
