vfs: fix vmplice_to_user() Commit 6130f5315ee8 "switch vmsplice_to_user() to copy_page_to_iter()" in v3.15-rc1 broke vmsplice(2). This patch fixes two bugs: - count is not initialized to a proper value, which resulted in no data being copied - if rw_copy_check_uvector() returns negative then the iov might be leaked. Tested OK.
