Fix two crashes with display of R2L lines in GUI sessions.

 xdisp.c (next_element_from_buffer): Don't call
 bidi_paragraph_init if we are at ZV.  Fixes a crash when reseated to
 ZV by try_window_reusing_current_matrix.
 (display_and_set_cursor, erase_phys_cursor): Handle negative HPOS,
 which happens with R2L glyph rows.  Fixes a crash when inserting a
 character at end of an R2L line.
