halapi: Fix fault by using backend instance before dlclose backend library

When try to use backend->name, backend->vendor variables
after dlclose(handle) of HAL backend shared library, segmentation fault happen.
So that move dlclose(hanlde) at the end of hal_common_put_backend() to
fix the segmentation fault.
