lzma: Relax memory limit for lzma decompressor
The kexec cannot load LZMA compressed vmlinuz.efi on LoongArch.
Try LZMA decompression.
lzma_decompress_file: read on /tmp/Image4yyfhM of 65536 bytes failed
pez_prepare: decompressed size 8563960
pez_prepare: done
Cannot load vmlinuz.efi
The root cause is that lzma decompressor requires more memory usage,
which exceeds the current 64M limit.
