bcachefs: Fix type of flags parameter for some ->trigger() implementations
When building with clang's -Wincompatible-function-pointer-types-strict
(a warning designed to catch potential kCFI failures at build time),
there are several warnings along the lines of:
fs/bcachefs/bkey_methods.c:118:2: error: incompatible function pointer types initializing 'int (*)(struct btree_trans *, enum btree_id, unsigned int, struct bkey_s_c, struct bkey_s, enum btree_iter_update_trigger_flags)' with an expression of type 'int (struct btree_trans *, enum btree_id, unsigned int, struct bkey_s_c, struct bkey_s, unsigned int)' [-Werror,-Wincompatible-function-pointer-types-strict]

fs/bcachefs/inode.h:26:13: note: expanded from macro 'bch2_bkey_ops_inode'
26 | .trigger = bch2_trigger_inode, \
| ^~~~~~~~~~~~~~~~~~
There are several functions that did not have their flags parameter
converted to 'enum btree_iter_update_trigger_flags' in the recent
unification, which will cause kCFI failures at runtime because the
types, while ABI compatible (hence no warning from the non-strict
version of this warning), do not match exactly.
Fix up these functions (as well as a few other obvious functions that
should have it, even if there are no warnings currently) to resolve the
warnings and potential kCFI runtime failures.
Fixes: 31e4ef3280c8 ("bcachefs: iter/update/trigger/str_hash flag cleanup")
