parsers: drop spurious check of readlen value

We're about to check if len < 40 after assigning readlen to len, which
means that if len < 40 we'll still abort, but I'm about to add a
sensible exception to that failure, so let's just discard this useless
check.

from mercurial.hg import parseurl

def testparse(url, branch=[]):
    print '%s, branches: %r' % parseurl(url, branch)

testparse('http://example.com/no/anchor')
testparse('http://example.com/an/anchor#foo')
testparse('http://example.com/no/anchor/branches', branch=['foo'])
testparse('http://example.com/an/anchor/branches#bar', branch=['foo'])
testparse('http://example.com/an/anchor/branches-None#foo', branch=None)
testparse('http://example.com/')
testparse('http://example.com')
testparse('http://example.com#foo')
