[PATCH] tools/tests: Make E2BIG non-fatal to xenstore unit test

[Kevin Stefanov]

Xenstore's unit test fails on read and write of big numbers if
quota-maxsize is set to a lower number than those test cases use.

Output a special warning instead of a failure message in such cases
and make the error non-fatal to the unit test.

Why not use E2BIG instead of the literal 7 here?

And please adhere to the coding style! There are some blanks missing and
the '{' wants to go into a separate line.

Not setting ret to 0 here will result in Xenstore not being cleaned up
after the test.
