patch 9.1.0577: Unnecessary checks for v:sizeoflong in test_put.vim

Problem:  Unnecessary checks for v:sizeoflong in test_put.vim.  They are
          no longer necessary as patch 8.2.3661 has changed the count to
          be within 32-bit integer limit.
Solution: Remove the checks (zeertzjq).

closes: #15239
