cmdutil: remove useless dirstate.normallookup() invocation in revert()

Explicit 'dirstate.normallookup()' invocation in 'revert()' is useless
now, because previous patch fixed the relevant issue by writing
in-memory dirstate changes out at the end of dirty check.

'dirstate.normallookup()' invocation was introduced by 21b33f0460e0 to
avoid occasional test failure (see issue4583 for detail). This is
partial backout of it (added tests are still left).
