[SCSI] ch: fix sparse shadowed variable warnings
Replace the global err array with ch_err.
drivers/scsi/ch.c:271:6: warning: symbol 'err' shadows an earlier one
drivers/scsi/ch.c:116:3: originally declared here
Replace the temporary cmd buffer with ch_err to avoid shadowing the cmd
function parameter.
drivers/scsi/ch.c:724:11: warning: symbol 'cmd' shadows an earlier one
