scsi: hisi_sas: Switch back to original libsas event notifiers

libsas event notifiers required an extension where gfp_t flags must be
explicitly passed. For bisectability, a temporary _gfp() variant of such
functions were added. All call sites then got converted use the _gfp()
variants and explicitly pass GFP context. Having no callers left, the
original libsas notifiers were then modified to accept gfp_t flags by
default.

Switch back to the original libas API, while still passing GFP context.
The libsas _gfp() variants will be removed afterwards.
