From: Tedd Ho-Jeong An <tedd.an@intel.com>

When the GError variable is freeed with g_error_free(), it is not set to
NULL and reusing the same variable again can cause the seg_fault because
it is still pointing the old memory address which is freed.

This patch relaces the g_error_free() to g_clear_error() which frees the
variable and set it to NULL if the variable is used in the function
again.

Fixes: 2287c517ca1bd ("adapter: Fix unchecked return value")
Fixes: https://github.com/bluez/bluez/issues/276
