Alexander Potapenko d2f459e3fe net: don't call strlen on non-terminated string in dev_set_alias() 
[ Upstream commit c28294b941 ]

KMSAN reported a use of uninitialized memory in dev_set_alias(),
which was caused by calling strlcpy() (which in turn called strlen())
on the user-supplied non-terminated string.
