fuse: ioctl: remove unnecessary comparison in fuse_setup_measure_verity()

Clang reports a warning in fuse_setup_measure_verity() when comparing
the __u16 digest_size with SIZE_MAX minus the size of struct
fsverity_digest:

	warning: result of comparison of constant 18446744073709551611 with
	expression of type '__u16' (aka 'unsigned short') is always false
	[-Wtautological-constant-out-of-range-compare]

This was first observed while building an x86_64 kernel with Clang and
W=1. Since -Werror was enabled in my build, the warning caused the build
to fail.

The same warning can also be reproduced with the same build options
using tinyconfig with FUSE enabled, so this is not specific to the
kernel configuration used in the original build.

The comparison is between the 16-bit digest_size and a size_t-sized
constant. Since this comparison cannot be true, remove it.
