Audio: mixin_mixout: 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.

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