[PATCH v3 4/4] spl: fit: improve spl_nand_fit_read(...) readability

[Dario Binacchi]

Replacing the ret variable with err and handling first the error
condition about the value returned by the spl_nand_fit_read routine,
improves the code readability.
Furthermore, the 'else' int the 'else return ret' instruction was
useless.
