[RFA/mi] Remove varobj enumeration XFAIL

[Keith Seitz <keiths@redhat.com>]

Hi,

mi{,2}-var-display.exp contains an XFAIL for the following test:

# Test: c_variable-7.51
# Desc: value of e
mi_gdb_test "-var-evaluate-expression e" \
	"\\^done,value=\"FIXME\"" \
	"eval variable e"

There is no bug filed for this (or for any of the other twenty-six 
setup_xfail calls in gdb.mi/), and I could find no history of why this 
was expected to fail. AFAICT, it has been this way from the beginning.

I suspect that this was xfailed because the test originally stopped in 
the beginning of the function, and there was no way to (easily?) get the 
value of the initialized enum.

But that all changed with this commit:
http://sourceware.org/ml/gdb-patches/2008-04/msg00007.html

This xfail no longer seems necessary, so I've attached a patch to fix 
the test case and remove the XFAIL.
