accel/amdxdna: Fix NULL pointer dereference of mgmt_chann

In the Linux kernel, the following vulnerability has been resolved:

accel/amdxdna: Fix NULL pointer dereference of mgmt_chann

mgmt_chann may be set to NULL if the firmware returns an unexpected
error in aie2_send_mgmt_msg_wait(). This can later lead to a NULL
pointer dereference in aie2_hw_stop().

Fix this by introducing a dedicated helper to destroy mgmt_chann
and by adding proper NULL checks before accessing it.
