[PATCH] staging: mfd: hi6421-spmi-pmic: fix error return code in hi6421_spmi_pmic_probe()

[Wang Hai]

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: 4524ac56cdca ("staging: mfd: add a PMIC driver for HiSilicon 6421 SPMI 
version")
