This\ncan lead to an unexpected \"BUG: kernel NULL pointer dereference\" if\nthe corresponding decompressor isn't built-in.\n\nFix this by checking against `sbi->available_compr_algs` for each\nm_algorithmformat request.  Incorrect !erofs_sb_has_compr_cfgs preset\nbitmap is now fixed together since it was harmless previously."
