pcmcia: fix return value of soc_pcmcia_regulator_set
The newly introduced soc_pcmcia_regulator_set() function sometimes
returns without setting its return code, as shown by this warning:
drivers/pcmcia/soc_common.c: In function 'soc_pcmcia_regulator_set':
drivers/pcmcia/soc_common.c:112:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This changes it to propagate the regulator_disable() result instead.
Fixes: ac61b6001a63 ("pcmcia: soc_common: add support for Vcc and Vpp regulators")
