net/core: Document all dev_ioctl() arguments
This patch avoids that the following warnings are reported when building
with W=1:
net/core/dev_ioctl.c:378: warning: Function parameter or member 'ifr' not described in 'dev_ioctl'
net/core/dev_ioctl.c:378: warning: Function parameter or member 'need_copyout' not described in 'dev_ioctl'
net/core/dev_ioctl.c:378: warning: Excess function parameter 'arg' description in 'dev_ioctl'
Cc: Al Viro <viro@zeniv.linux.org.uk>
