Currently, zram dynamically allocates memory for compressor algorithm names when they are set by the user. This requires careful memory management, including explicit `kfree` calls and special handling to avoid freeing statically defined default compressor names. This patch refactors the way zram handles compression algorithm names. Instead of storing dynamically allocated copies, `zram->comp_algs` will now store pointers directly to the static name strings defined within the `zcomp_ops` backend structures, thereby removing the need for conditional `kfree` calls.
