platform: mellanox: Change "reset_pwr_converter_fail" attribute

Change "reset_voltmon_upgrade_fail" attribute name to
"reset_pwr_converter_fail".

For systems using "mlxplat_mlxcpld_default_ng_regs_io_data", relevant
CPLD 'register.bit' indicates the failure of power converter, while on
older systems same 'register.bit' indicates failure of voltage monitor
devices upgrade failure.
