io_uring: fix memleak in io_sqe_files_register()
I got a memleak report when doing some fuzz test:
BUG: memory leak
unreferenced object 0x607eeac06e78 (size 8):
comm "test", pid 295, jiffies 4294735835 (age 31.745s)
hex dump (first 8 bytes):
00 00 00 00 00 00 00 00 ........
backtrace:
[<00000000932632e6>] percpu_ref_init+0x2a/0x1b0
[<0000000092ddb796>] __io_uring_register+0x111d/0x22a0
[<00000000eadd6c77>] __x64_sys_io_uring_register+0x17b/0x480

[<00000000864a281d>] entry_SYSCALL_64_after_hwframe+0x44/0xa9
Call percpu_ref_exit() on error path to avoid
refcount memleak.
