From: Rui Miguel Silva <rui.silva@linaro.org>
caam_remove already removes the debugfs entry, so we need to remove the one immediately before calling caam_remove.
This fix a NULL dereference at error paths is caam_probe fail.
[bod: changed name prefix to "crypto: caam: Fix .."] [bod: added Fixes tag]
Fixes: 67c2315def06 ("crypto: caam - add Queue Interface (QI) backend support")
