qcacmn: Replace kzalloc/kfree with vmalloc/vfree

Browse Source 
At continuous physical address limited telematics platform,
in order to avoid occasional memory alloc failure with big
kzalloc size, it's better to use virtual memory allocation
API instead. And below items will be refined to replace
malloc with valloc if CONFIG_ENABLE_VALLOC_REPLACE_MALLOC=y.

1 x 30488 = 30488B @dp_soc_attach:15189
1 x 52096 = 52096B @hal_attach:1104
4096 x 64 = 262144B @dp_rx_desc_pool_alloc:337
