Help the compiler out by adding an explicit limit here to make the code slightly more robust and avoid the warning.

Instead of strcpy'ing into a stack buffer, just let additional_notice point to a string literal living in .rodata. This is better in a few ways: - Smaller .text - instead of gcc compiling the strcpys as a bunch of immediate stores (effectively encoding the string literal in the instruction stream), we only pay the price of storing the literal in .rodata. - Faster, because there's no string copying. - Smaller stack usage (with my compiler, 72 bytes instead of 176 for the sole caller, bnx2i_indicate_kcqe) Moreover, it's currently possible for additional_notice[] to get used uninitialized, so some random stack garbage would be passed to printk() - in the worst case without any '\0' anywhere in those 64 bytes. That could be fixed by initializing additional_notice[0], but the same is achieved here by initializing the new pointer variable to "". Also give the message pointer a similar treatment - there's no point making temporary copies on the stack of those two strings.
