docs/memory-barriers.txt: Add a missed closing parenthesis

The description of io_stop_wc(), which was added by commit d5624bb29f
("asm-generic: introduce io_stop_wc() and add implementation for ARM64"),
has an unclosed parenthesis.  This commit closes it.

@ -1966,7 +1966,7 @@ There are some more advanced barrier functions:
(*) io_stop_wc();
For memory accesses with write-combining attributes (e.g. those returned
by ioremap_wc(), the CPU may wait for prior accesses to be merged with
by ioremap_wc()), the CPU may wait for prior accesses to be merged with
subsequent ones. io_stop_wc() can be used to prevent the merging of
write-combining memory accesses before this macro with those after it when
such wait has performance implications.
