[Intel-gfx] [PATCH 1/1] tests/gem_reset_stats: EPERM check not needed

[Mika Kuoppala]

Without root we used to get EPERM if we tried to aquire
default context statistics. Now we have per fd statistics
so only thing which is hidden from us without root access,
is the global reset count.

Drop EPERM and check that global reset count is always zero
for nonroot.
