Subject: [PATCH -next] io_uring: Add missing inline to io_uring_cmd_import_fixed() dummy

If CONFIG_IO_URING is not set:

    include/linux/io_uring.h:65:12: error: ‘io_uring_cmd_import_fixed’ defined but not used [-Werror=unused-function]
       65 | static int io_uring_cmd_import_fixed(u64 ubuf, unsigned long len, int rw,
	  |            ^~~~~~~~~~~~~~~~~~~~~~~~~

Fix this by adding the missing "inline" keyword.
