irda: prevent heap corruption on invalid nickname
commit d50e7e3604778bfc2dc40f440e0742dbae399d54 upstream. Invalid nicknames containing only spaces will result in an underflow in a memcpy size calculation, subsequently destroying the heap and panicking. v2 also catches the case where the provided nickname is longer than the buffer size, which can result in controllable heap corruption.
