The problem with MariaDB waiting was fixed earlier.
However the server still gives the old error,in case of disk full,
that includes "waiting for someone to free some space" even if
there is now wait.
This commit changes the error message for the non waiting case to:
Disk got full writing 'db.table' (Errcode: 28 "No space left on device")
Disk got full writing 'test.t1' (Errcode: 28 "No space left on device")Disk got full writing 'test.t1' (Errcode: 28 "No space left on device")Disk got full writing 'test.t1' (Errcode: 28 "No space left on device")
