[PATCH] btrfs: Remove unused page_to_{inode,fs_info} macros

[PATCH] btrfs: Remove unused page_to_{inode,fs_info} macros

[Youling Tang]

From: Youling Tang <tangyouling@kylinos.cn>

This macro is no longer used after the "btrfs: Cleaned up folio->page
conversion" series patch [1] was applied, so remove it.
