Subject: wlcore: fix error handling in wlcore_event_fw_logger

From: Andrzej Hajda <a.hajda@samsung.com>

commit 68f37e5d7a2e00306adab033fba6c3042b33e8e1 upstream.

wlcore_read/wlcore_write can return negative values so it should
be assigned to signed variable.

The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci [1].
