kmodloader: fix invalid read outside mapped region

Code parsing .modinfo data skips over null sequences without checking
bounds and may read past mapped memory, potentially triggering SIGSEGV.

Fixes: https://github.com/openwrt/openwrt/issues/14463
Fixes: d6e6825c4697 ("add support for module handling")
Refer: 9371411715c8 ("kmodloader: fix out-of-bound access when parsing .modinfo")
