serial: sprd: correct the wrong sequence of arguments
commit 9c801e313195addaf11c16e155f50789d6ebfd19 upstream. The sequence of arguments which was passed to handle_lsr_errors() didn't match the parameters defined in that function, &lsr was passed to flag and &flag was passed to lsr, this patch fixed that.
