Jann Horn f6a6768462 netfilter: nf_log: fix uninit read in nf_log_proc_dostring 
[ Upstream commit dffd22aed2aa1e804bccf19b30a421e89ee2ae61 ]

When proc_dostring() is called with a non-zero offset in strict mode, it
doesn't just write to the ->data buffer, it also reads. Make sure it
doesn't read uninitialized data.

Fixes: c6ac37d8d884 ("netfilter: nf_log: fix error on write NONE to [...]")
