init: allow blacklisting of module_init functions

sprint_symbol_no_offset() returns the string "function_name
[module_name]" where [module_name] is not printed for built in kernel
functions.  This means that the blacklisting code will fail when
comparing module function names with the extended string.

This patch adds the functionality to block a module's module_init()
function by finding the space in the string and truncating the
comparison to that length.
