n-acd: fix handling of N_ACD_E_DROPPED

Browse source 
N_ACD_E_DROPPED is an error code of n-acd, albeit internal. But such codes are returned
as postive values, unlike error codes from errno.h (which are negative).

Fix comparing for N_ACD_E_DROPPED, otherwise the error gets propagate to the caller
when we should handle it internally.
