Audio: Selector: 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 IPC3 implementation of selector uses the component interface
directly and can not use the new module API.
