[PATCH 2/2] net: can: comparison of unsigned variable

[Sudip Mukherjee <sudipm.mukherjee@gmail.com>]

err was of the type u32. it was being compared with < 0, and being
an unsigned variable the comparison would have been always false.

moreover, err was getting the return value from set_reset_mode()
and xcan_set_bittiming(), and both are returning int.
