The request to aqquire gem resources is failing for DSB in rare
scenario where it is busy and the register programming will be done
through mmio fallback path.
DSB has extra advantage of faster register programming which may
go away through mmio path. Adding wait for gem resource also may
not be right as anyways losing time.
To make the CI execution happy replaced drm_dbg_kms() to drm_info()
for printing debuf info during dsb buffer preparation.

If CI is happy with drm_warn then it makes sense to use drm_warn.

These messages are bit vague, add "DSB VMA creation failed" or something
similar.
