[GIT PULL] etnaviv-fixes for 5.4

[Lucas Stach]

Hi Dave, hi Daniel,

a few small fixes for the etnaviv driver.

One memory corruption fix in the MMUv2 GPU coredump code, a deadlock
fix also in the coredump code and reintroduction of a helpful message,
which got dropped by accident in this cycle.

Regards,
Lucas
