serial: sprd: correct the wrong sequence of arguments 

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.

Fixes: b7396a38fb ("tty/serial: Add Spreadtrum sc9836-uart driver support")
