[PATCH 1/2] spi: sprd: Don't skip cleanup in remove's error path

[Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>]

If pm_runtime_resume_and_get() failed before this change, two error
messages were printed. One directly in sprd_spi_remove() and another
by the device core as the return value is non-zero.

The better handling of a failure to resume the device is to do the
software related cleanup anyhow and only skip hardware accesses.
This leaves the device in an unknown state, but there is nothing that can
be done about that.

Even in the error case, return zero to suppress the device core's error
message.
