padata: fix uninitialized return value in padata_replace() ...
[ Upstream commit 41ccdbfd5427bbbf3ed58b16750113b38fad1780 ]
According to Geert's report[0],
kernel/padata.c: warning: 'err' may be used uninitialized in this
function [-Wuninitialized]: => 539:2
Warning is seen only with older compilers on certain archs. The
runtime effect is potentially returning garbage down the stack when
padata's cpumasks are modified before any pcrypt requests have run.
Simplest fix is to initialize err to the success value.
