zram: reject unrecognized type= values in recompress_store()
recompress_store() parses the type= parameter with three if statements
checking for "idle", "huge", and "huge_idle". An unrecognized value
silently falls through with mode left at 0, causing the recompression pass
to run with no slot filter — processing all slots instead of the
intended subset.
Add a !mode check after the type parsing block to return -EINVAL for
unrecognized values, consistent with the function's other parameter
validation.
