This reverts commit f86b9bf6228bb334fe1addcd566a658ecbd08f7e which is commit f4ac712e4fe009635344b9af5d890fe25fcc8c0d upstream.

Above change "block: ratelimit handle_bad_sector() message" upstream commit f4ac712e4fe009635344b9af5d890fe25fcc8c0d in 4.19.154 kernel is not completely OK.
Removing casts from arguments 4 and 5 produces these compile warnings:
...
For 64 bit systems it is only compile time cosmetic warning. For 32 bit system + CONFIG_LBDAF=n it introduces bugs: output formats are "%llu" and passed parameters are 32 bits. That is not OK.
Upstream kernels have hardcoded 64 bit sector_t. In older stable trees sector_t can be either 64 or 32 bit. In other words, backport of above patch needs to keep those original casts.
And Tetsuo Handa writes: Indeed, commit f4ac712e4fe00963 ("block: ratelimit handle_bad_sector() message") depends on commit 72deb455b5ec619f ("block: remove CONFIG_LBDAF") which was merged into 5.2 kernel.
So let's revert it.
