scsi: hisi_sas: Fix tag freeing for reserved tags
The reserved tags were put in the lower region of the tagset in commit f7d190a94e35 ("scsi: hisi_sas: Put reserved tags in lower region of tagset"). However, only the allocate function was changed, freeing was not handled. This resulted in a failure to boot: [ 33.467345] hisi_sas_v3_hw 0000:b4:02.0: task exec: failed[-132]!
