Contribution description

The nrfmin driver had a serious bug terminating the interrupt handler in case of an invalid CRC value.
Instead of closing with cortexm_isr_end(); it just returned, which resulted in unwanted behaviour.

This PR fixes one error mentioned in #10878 and is based on the solution of @pystub

Testing procedure

Testing should at least involve receiving and then sending packets with a valid CRC. However, it is appreciated if a reviewer makes sure that the behaviour is also correct with invalid CRC.

Make sure to test it using nrfmin with USEMODULE=nrfmin on nrf5x boards.

Seems obvious. But I still want to test. ACK on the rest though

Mh... I wasn't able to reproduce the issue, but during my testing I found the following problem: When I ping from two nodes simultaneously

ping6 ff02::1 -c 1000 -i 10

everything works fine, however when I then do

ping6 ff02::1 -c 10000 -i 0

the first command doesn't work anymore afterwards. I'll have a look if this is isolated to nrfmin and report in a separate issue. However, this has nothing to do with this PR, so ACK.
