usb: host: r8a66597-hcd: Remove set, then over-written, but never used variable 'tmp'

Looks like it's been this way since the driver's inception in 2007.

Fixes the following W=1 kernel build warning(s):

 drivers/usb/host/r8a66597-hcd.c: In function ‘clear_all_buffer’:
 drivers/usb/host/r8a66597-hcd.c:478:6: warning: variable ‘tmp’ set but not used [-Wunused-but-set-variable]
 478 | u16 tmp;
 | ^~~
