Arnd Bergmann a2b6d56416 scsi: bfa: Fix function pointer type mismatch for hcb_qe->cbfn
[ Upstream commit b69600231f751304db914c63b937f7098ed2895c ]

Some callback functions used here take a boolean argument, others take a
status argument. This breaks KCFI type checking, so clang now warns about
the function pointer cast:

drivers/scsi/bfa/bfad_bsg.c:2138:29: error: cast from 'void (*)(void *, enum bfa_status)' to 'bfa_cb_cbfn_t' (aka 'void (*)(void *, enum bfa_boolean)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]

Assuming the code is actually correct here and the callers always match the
argument types of the callee, rework this to replace the explicit cast with
a union of the two pointer types. This does not change the behavior of the
code, so if something is actually broken here, a larger rework may be
necessary.
