[PATCH v2 1/1] net sysfs: Print link speed as signed integer

[Alexander Stein]

Otherwise 4294967295 (MBit/s) (-1) will be printed when there is no link.
Documentation/ABI/testing/sysfs-class-net does not state if this shall be
signed or unsigned.
Also remove the now unused variable fmt_udec.

Signed-off-by: Alexander Stein <alexander.stein@xxxxxxxxxxxxxxxxxxxxx>

Changes in v2:
* Switch the format specifier instead of changing it
* Remove the now unused variable
