drm/xe: Faster devcoredump
The current algorithm to read out devcoredump is O(N*N) where N is the
size of coredump due to usage of the drm_coredump_printer in
xe_devcoredump_read. Switch to a O(N) algorithm which prints the
devcoredump into a readable format in snapshot work and update
xe_devcoredump_read to memcpy from the readable format directly.
v2:
- Fix double free on devcoredump removal (Testing)
- Set read_data_size after snap work flush
- Adjust remaining in iterator upon realloc (Testing)
- Set read_data upon realloc (Testing)
