netlink: Fix printing of zero-length prefixes
When delinearizing, an all-zero mask didn't qualify as prefix. Therefore
a statement:
| ip daddr 0.0.0.0/0
would be printed as:
| ip daddr & 0.0.0.0 == 0.0.0.0
To fix this, expr_mask_is_prefix() must return true if the initial 1-bit
search fails (the given value must be zero in this case). Additionally,
a shortcut is needed in conversion algorithm of expr_mask_to_prefix()
to not turn the zero prefix into a 1 by accident.
