net: fix some identation issues at kernel-doc markups

Sphinx is very pedantic with regards to identation and
escape sequences:

  ./include/net/sock.h:1967: ERROR: Unexpected indentation.
  ./include/net/sock.h:1969: ERROR: Unexpected indentation.
  ./include/net/sock.h:1970: WARNING: Block quote ends without a blank line; unexpected unindent.
  ./include/net/sock.h:1971: WARNING: Block quote ends without a blank line; unexpected unindent.
  ./include/net/sock.h:2268: WARNING: Inline emphasis start-string without end-string.
  ./net/core/sock.c:2686: ERROR: Unexpected indentation.
  ./net/core/sock.c:2687: WARNING: Block quote ends without a blank line; unexpected unindent.
  ./net/core/datagram.c:182: WARNING: Inline emphasis start-string without end-string.
  ./include/linux/netdevice.h:1444: ERROR: Unexpected indentation.
  ./drivers/net/phy/phy.c:381: ERROR: Unexpected indentation.
  ./drivers/net/phy/phy.c:382: WARNING: Block quote ends without a blank line; unexpected unindent.

- Fix spacing where needed;
- Properly escape constants;
- Use a literal block for a race description.

No functional changes.
