'ret' hasn't  been checked since the driver's inception in 2009.

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

 drivers/usb/early/ehci-dbgp.c: In function ‘early_dbgp_write’:
 drivers/usb/early/ehci-dbgp.c:915:13: warning: variable ‘ret’ set but not used [-Wunused-but-set-variable]
 915 | int chunk, ret;
