Avoid warnings about comparisons that are always true.

Browse Source 
The range of "enum" types varies from one ABI to another.  If the enums
being tested in these functions happen to be 16 bits wide, then GCC may
issue a warning because, in such a case, the comparison is always true.

Using an int instead of a uint16_t avoids that particular problem and
should suppress the warning.

Fixes the following reported warnings:

lib/ofp-print.c:240: warning: comparison is always true due to limited
range of data type
lib/ofp-util.c:1973: warning: comparison is always false due to limited
range of data type
