spi: s3c64xx: Fix pm_runtime_get_sync() return value check
If the device is already in a runtime PM enabled state
pm_runtime_get_sync() will return 1, so a test for negative
value should be used to check for errors.
Without this patch there are seen errors like:
[ 8.540000] s3c64xx-spi 13930000.spi: Failed to enable device: 1
[ 8.545000] spi_master spi1: failed to prepare transfer hardware
Likely because the driver uses synchronous API to runtime enable
the device and asynchronous one to disable it.
