scsi: pm8001: Fix tag leaks on error

In the Linux kernel, the following vulnerability has been resolved:

scsi: pm8001: Fix tag leaks on error

In pm8001_chip_set_dev_state_req(), pm8001_chip_fw_flash_update_req(),
pm80xx_chip_phy_ctl_req() and pm8001_chip_reg_dev_req() add missing calls
to pm8001_tag_free() to free the allocated tag when pm8001_mpi_build_cmd()
fails.

Similarly, in pm8001_exec_internal_task_abort(), if the chip ->task_abort
method fails, the tag allocated for the abort request task must be
freed. Add the missing call to pm8001_tag_free().
