Fix Wswitch-enum and Wcast-qual compiler warnings

Browse Source 
The function nmbs_strerror does not handle the error code
NMBS_ERROR_INVALID_UNIT_ID inside the switch statement, which triggers
the GCC/Clang Wswitch-enum warning. Adding a new case inside the switch
statement solves this warning.

There is a cast from a const void pointer to an uint8_t pointer inside
the function nmbs_send_raw_pdu, which triggers the GCC/Clang Wcast-qual
warning. Adding the missing const qualifier solves this warning.
