mm: do not recache pages at the end of playback

Browse Source 
PD#SWPL-700

Problem:

The reset action will re-allocate the memory before the end of playback.
At this time, the codec_mm_scatter_mgt_delay_free_swith will raise the
cache pages from 20M to force_cache_page_cnt, resulting in redundant
allocation, resulting in memory fragmentation and more time-consuming
in reset action.

Solution:
Modify the judgment cache condition.

Verify:
