[PATCH] scsi: csiostor: Uninitialized data in csio_ln_vnp_read_cbfn()

[Dan Carpenter]

This variable is just a temporary variable, used to do an endian
conversion.  The problem is that the last byte is not initialized.
After the conversion is completely done, the last byte is discarded so
it doesn't cause a problem.  But static checkers and the KMSan runtime
checker can detect the uninitialized read and will complain about it.

Fixes: 5036f0a0ecd3 ("[SCSI] csiostor: Fix sparse warnings.")
