powerpc/powernv: Use ssize_t for sysparam return values
The OPAL calls are returning int64_t values, which the sysparam code stores in an int, and the sysfs callback returns ssize_t. Make code a easier to read by consistently using ssize_t. Signed-off-by: Joel Stanley <joel@jms.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
