From: Tedd Ho-Jeong An <tedd.an@xxxxxxxxx>
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: 4ad622d592ba5 ("profiles/a2dp: Fix unchecked return value")
