[PATCH v6 3/8] kho: Include linux/mm.h in kho_block.c

[George Guo]

From: George Guo <guodongtai@xxxxxxxxxx>

kho_block.c calls virt_to_phys() and phys_to_virt(). With CONFIG_KFENCE=y,
the LoongArch implementations use offset_in_page() and page_address(),
which are provided by <linux/mm.h>.

Include <linux/mm.h> explicitly to avoid implicit-declaration build
errors for these helpers.
