Fix corruption of encoding name string
[Bug #20595]
enc_set_default_encoding will free the C string if the encoding is nil,
but the C string can be used by the encoding name string. This will cause
the encoding name string to be corrupted.
Consider the following code:
Encoding.default_internal = Encoding::ASCII_8BIT
names = Encoding.default_internal.names
p names
Encoding.default_internal = nil
p names
It outputs:
["ASCII-8BIT", "BINARY", "internal"]
["ASCII-8BIT", "BINARY", "\x00\x00\x00\x00\x00\x00\x00\x00"]
