Subject[PATCH v4 47/52] docs: mei.rst: fix a C expression markup
Sphinx 3.x doesn't allow expressions using :c:func markup:

./Documentation/driver-api/mei/mei.rst:41: WARNING: Unparseable C cross-reference: 'close(int fd)'
Invalid C declaration: Expected end of definition. [error at 5]
close(int fd)

So, convert it into a :c:expr.
