fs: use splice_copy_file_range() inline helper
generic_copy_file_range() is just a wrapper around splice_file_range(),
which caps the maximum copy length.
The only caller of splice_file_range(), namely __ceph_copy_file_range()
is already ready to cope with short copy.
Move the length capping into splice_file_range() and replace the exported
symbol generic_copy_file_range() with a simple inline helper.
