6.13-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit cf4d74256fe103ece7b2647550e6c063048e5682 ]
While 'stack_dump_size' is a u32 bitfield of 16 bits, u32 has a bigger upper bound than the type u16 of loop counter 'offset' what in theory may lead to infinite loop condition.
Found out by Coverity static analyzer.
