scsi: storvsc: Log TEST_UNIT_READY errors as warnings
Commit 08f76547f08d ("scsi: storvsc: Update error logging") added more
robust logging of errors, particularly those reported as Hyper-V
errors. But this change produces extra logging noise in that
TEST_UNIT_READY may report errors during the normal course of detecting
device adds and removes.
Fix this by logging TEST_UNIT_READY errors as warnings, so that log lines
are produced only if the storvsc log level is changed to WARN level on the
kernel boot line.
