param: fix setting arrays of bool
commit 3c7d76e371ac1a3802ae1673f5c63554af59325c upstream.
We create a dummy struct kernel_param on the stack for parsing each
array element, but we didn't initialize the flags word. This matters
for arrays of type "bool", where the flag indicates if it really is
an array of bools or unsigned int (old-style).
