Kprobes: Make kprobe.symbol_name const

From: Ananth N Mavinakayanahalli <[email protected]>

Kprobes doesn't scribble the kprobe.symbol_name field. Its only set by the module when registering the probe. Modules that exercise good hygiene using the "const" qualifier will see warnings...

warning: assignment discards qualifiers from pointer target type

Make struct kprobe.symbol_name const char *
