scsi: pm8001: Remove pm8001_tag_init()

In commit 5a141315ed7c ("scsi: pm80xx: Increase the number of outstanding
I/O supported to 1024") the pm8001_ha->tags allocation was moved into
pm8001_init_ccb_tag(). This changed the execution order of allocation.
pm8001_tag_init() used to be called after the pm8001_ha->tags allocation
and now it is called before the allocation.

Before:

pm8001_pci_probe()
`--> pm8001_pci_alloc()
     `--> pm8001_alloc()
          `--> pm8001_ha->tags = kzalloc(...)
          `--> pm8001_tag_init(pm8001_ha); // OK: tags are allocated

After:

pm8001_pci_probe()
`--> pm8001_pci_alloc()
|    `--> pm8001_alloc()
|         `--> pm8001_tag_init(pm8001_ha); // NOK: tags are not allocated
|
`--> pm8001_init_ccb_tag()
     `-->  pm8001_ha->tags = kzalloc(...) // today it is bitmap_zalloc()

Since pm8001_ha->tags_num is zero when pm8001_tag_init() is called it does
nothing. Tags memory is allocated with bitmap_zalloc() so there is no need
to manually clear each bit with pm8001_tag_free().
