serial: sh-sci: Remove bogus sci_handle_fifo_overrun() call on (H)SCIF

Commit 8b6ff84c2d445a47 ("serial: sh-sci: Fix R-Car SCIF and HSCIF
overrun handling") added overrun handling for (H)SCIF using the SCLSR
register, but also accidentally added a bogus call to
sci_handle_fifo_overrun() in the receive interrupt path.

Remove it again.
