RX buffer allocation has been reworked in current dev tree. The
objective is to support multiple buffers per QCS to improve upload
throughput.
RX buffer allocation failure is handled simply : the whole connection is
closed. This is done via qcc_set_error(), with INTERNAL_ERROR as error
code. This function contains a BUG_ON() to ensure it is called only one
time per connection instance.
On RX buffer alloc failure, the aformentioned BUG_ON() crashes due to a
double invokation of qcc_set_error(). First by qcs_get_rxbuf(), and
immediately after it by qcc_recv(), which is the caller of the previous
one. This regression was introduced by the following commit.

MAJOR: mux-quic: support multiple QCS RX buffers
To fix this, simply remove qcc_set_error() invocation in
qcs_get_rxbuf(). On buffer alloc failture, qcc_recv() is responsible to
set the error.
This does not need to be backported.
