net/smc: fix suppressed return code
The patch that repaired the invalid return code in smcd_new_buf_create() missed to take care of errno ENOSPC which has a special meaning that no more DMBEs can be registered on the device. Fix that by keeping this errno value during the translation of the return code. Fixes: 6b1bbf94ab36 ("net/smc: fix invalid return code in smcd_new_buf_create()") Signed-off-by: Karsten Graul <kgraul@linux.ibm.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
