Commit 
9e343e87d2c4 ("mtd: cfi: convert inline functions to macros")
changed map_word_andequal() into a macro, but also changed the right
hand side of the comparison from val3 to val2.  Change it back to use
val3 on the right hand side.
Thankfully this did not cause a regression because all callers
currently pass the same argument for val2 and val3.
