Fix memory leak in Magick::Draw for recentry ImageMagick 6 by removing unnecessary GetDrawInfo() calling

[Watson1978]

Fix #1401

Before	After

Test code

require 'rmagick'

3000.times do |i|
  img = Magick::Image.new(1000, 1000)

  gc = Magick::Draw.new
  gc.text(0, 67, 'Hello world!!')
  gc.draw(img)
end

[dlemstra]

This is the correct patch because AcquireDrawInfo already calls GetDrawInfo.
