Look at it as O=N-O-H, and you will see that all the bonds are covalent.
There are no dative covalent bonds in this structure.

HNO2 is a tautomeric mixture of nitrile and nitro forms. As you know, in nitriles the bonding is through O atom whereas in nitro it is through the N atom. Hence, when the bonding is through nitrogen, a double bond is formed with one O atom, a dative bond is formed with the other Oxygen atom and one H bond exists. O has 6 electrons in its outer most valence. If it shares one of its already existing electron with N then it now has 7 electrons.(disobeys octet). Nitrogen on the other hand has 5 electrons in the valence, which after double bonding with O and a single bonding with hydrogen has 6 electrons in the valence being shared(Nitrogen contributes 3). Hence shares the remaining two with the oxygen, and is the sole donor.
