ZVOL: Minor code cleanup

Browse Source 
- Remove zsda_tx field, it is used only once.
 - Remove unneeded string lengths checks, all names are terminated.
 - Replace few explicit MAXNAMELEN usages with sizeof().
 - Change dsname from MAXNAMELEN to ZFS_MAX_DATASET_NAME_LEN, as
expected by dsl_dataset_name().  Both are 256 bytes now, but it is
better to be safe.

This should have no functional difference.
