nvme: fix command limits status code

Browse Source 
The command specific status code, 0x183, was introduced in the NVMe 2.0
specification defined to "Command Size Limits Exceeded" and only ever
applied to DSM and Copy commands.  Fix the name and, remove the
incorrect translation to error codes and special treatment in the
target code for it.
