scsi: ibmvscsis: Ensure partition name is properly NUL terminated
[ Upstream commit adad633af7b970bfa5dd1b624a4afc83cac9b235 ]
While reviewing another part of the code, Kees noticed that the strncpy of the
partition name might not always be NUL terminated. Switch to using strscpy
which does this safely.
