[PATCH] include/net/inet_connection_sock.h: Use pr_devel() instead of pr_debug()

When DYNAMIC_DEBUG enabled, pr_debug() depends on KBUILD_MODNAME which
also depends on the modules name in Makefile.
Refer to the information in "scripts/Makefile.lib":

 # $(modname_flags) #defines KBUILD_MODNAME as the name of the module it will
 # end up in (or would, if it gets compiled in)
 # Note: Files that end up in two or more modules are compiled without the
 #       KBUILD_MODNAME definition. The reason is that any made-up name would
 #       differ in different configs.

File "inet_connection_sock.h" is a common share header that not can 
be use for one module, so use pr_devel instead of pr_debug is OK.
