Commit <f2e767bb> ("mpt3sas: Force request partial completion alignment") was not considering the case of commands not operating on logical block size units (e.g. REQ_OP_ZONE_REPORT and its 64B aligned partial replies). In this case, forcing alignment of resid to the device logical block size can break the command result, e.g. in the case of REQ_OP_ZONE_REPORT, the exact number of zone reported by the device. Move the partial completion alignement check of mpt3sas to a generic implementation in sd_done(). The check is added within the default section of the initial req_op() switch case so that the report and reset zone commands are ignored. In addition, as sd_done() is not called for passthrough requests, resid corrections are not done as intended by the initial mpt3sas patch.
