ata: libata-scsi: simplify __ata_scsi_queuecmd()
[ Upstream commit
84eac327af543f03172085d5ef9f98ea25a51191 ]
This patch cleans up the code of __ata_scsi_queuecmd(). Since each
branch of the "if" condition check that scmd->cmd_len is not zero, move
this check out of the "if" to simplify the conditions being checked in
the "else" branch.
While at it, avoid the if-else-if-else structure using if-else if
structure and remove the redundant rc local variable.
This patch does not change the function logic.
