[PATCH] ethdev: fix get_reg_info

[Thierry Herbelot]

'width' and 'offset' are input parameters when dumping the register
info of an Ethernet device. They should be copied in the new request
before calling the device callback function.

Fixes: 083db2ed9e9 ('ethdev: add report of register names and filter')
