is_valid_cidr raises TypeError if address is invalid

[Abhishek Kekane]

is_valid_cidr() will raise TypeError if invalid input is passed.

E.g.
is_valid_cidr(10)
will raise following error

Traceback (most recent call last):
  File "b.py", line 30, in <module>
    is_valid_cidr(10)
  File "b.py", line 15, in is_valid_cidr

  File "/Library/Python/2.7/site-packages/netaddr/ip/__init__.py", line 923, in __init__
    implicit_prefix, flags)
  File "/Library/Python/2.7/site-packages/netaddr/ip/__init__.py", line 818, in parse_ip_network
    raise TypeError('unexpected type %s for addr arg' % type(addr))
TypeError: unexpected type <type 'int'> for addr arg
