Audio: up_down_mixer: Memory, blob, and fast_get allocs to module API

Allocate all memory, blob handlers, and fast_get() buffers through
module API mod_alloc() and friends and remove all redundant rfree(),
comp_data_blob_handler_free(), and fast_put() calls from module unload
functions and init error branches. The two rballoc() calls are
converted to mod_balloc().

When resources are allocated through module API functions they
are automatically freed when the module is unloaded. This
simplifies error handling and unloading process.
