Drop the no_memory() call from zpool_in_use() when reading the
label fails and instead return the error to the caller. This
prevents a misleading "internal error: out of memory" error
when the label can't be read. This will result in is_spare()
returning B_FALSE instead of aborting, which is already safely
handled.
Furthermore, on Linux it's possible for EREMOTEIO to returned
by an NVMe device if the device has been low-level formatted
and not rescanned. In this case we want to fallback to the
legacy scanning method and read any of the labels we can.
