squashfs: allows users to configure the number of decompression threads
The maximum number of threads in the decompressor_multi.c file is fixed
and cannot be adjusted according to user needs. Therefore, the mount
parameter needs to be added to allow users to configure the number of
threads as required. The upper limit is num_online_cpus() * 2.
