[PATCH 6/9] nilfs2: fix out-of-range warning

From: Arnd Bergmann <arnd@arndb.de>

clang-14 points out that v_size is always smaller than a 64KB
page size if that is configured by the CPU architecture:

fs/nilfs2/ioctl.c:63:19: error: result of comparison of constant 65536 with expression of type '__u16' (aka 'unsigned short') is always false [-Werror,-Wtautological-constant-out-of-range-compare]
if (argv->v_size > PAGE_SIZE)
~~~~~~~~~~~~ ^ ~~~~~~~~~

This is ok, so just shut up that warning with a cast.
