padata: fix sysfs store callback check

[ Upstream commit 9ff6e943bce67d125781fe4780a5d6f072dc44c0 ]

padata_sysfs_store() was copied from padata_sysfs_show() but this check
was not adapted. Today there is no attribute which can fail this
check, but if there is one it may as well be correct.

Fixes: 5e017dc3f8bc ("padata: Added sysfs primitives to padata subsystem")
