A quote from the preface of THE HOBBIT on the spelling of the plural of dwarf :

In English the only correct plural of "dwarf" is "dwarfs", and the adjective is "dwarfish". In this story "dwarves" and "dwarvish" are used, but only when speaking of the ancient people to whom Thorin Oakenshield and his companions belonged.

This also accounts for the spellings throughout Tolkien's works.
