UPSTREAM: ath10k: qmi: Sleep for a while before assigning MSA memory

Browse source 
commit b70b3a36ec33a2c8d3292f3b33fe2047a8f57b9a upstream.

Unless we sleep for a while before transitioning the MSA memory to WLAN
the MPSS.AT.4.0.c2-01184-SDM845_GEN_PACK-1 firmware triggers a security
violation fairly reliably. Unforutnately recovering from this failure
always results in the entire system freezing.
