staging: dgrp: Drop unnecessary typecast
An unnecessary typecast in dgrp_net_ops.c causes the following build error
if compiled with W=1.
In function ‘copy_from_user’, inlined from ‘dgrp_net_ioctl’ at
drivers/staging/dgrp/dgrp_net_ops.c:3408:21:
arch/x86/include/asm/uaccess_32.h:211:26: error: call to
‘copy_from_user_overflow’ declared with attribute error: copy_from_user()
buffer size is not provably correct
