scsi: sd: Print write through due to no caching mode page as warning
For SD cardreaders it is extremely common not to have a cache.
Consequently, the following messages do not point to a real error one could
try to fix but rather describe how the disk works:
sd 0:0:0:0: [sda] No Caching mode page found
sd 0:0:0:0: [sda] Assuming drive cache: write through
Print these messages as warnings instead of errors.
