bcachefs: Simplify bch2_bio_map()

For the part of directly mapping the kernel virtual address, there is no
need to increase to bio page-by-page. It can be directly replaced by
bio_add_virt_nofail().

For the address part of the vmalloc region, its physical address is
discontinuous and needs to be increased page-by-page to bio. The helper
function bio_add_vmalloc() can be used to simplify the implementation of
bch2_bio_map().
