qcacld-3.0: Enable IPA when loaded as module

Currently, module 'm' is converted to 'y' in QGKI when
compiling. In Waipio, GKI2 is present in which 'm'
is not being converted and hence IPA_OFFLOAD is not enabled.
To fix this, checking if CONFIG_IPA3 is either set to y or m
and then enabling CONFIG_IPA_OFFLOAD.
From Kernel 5.10, few IPA functions are depreciated for which
putting the depreciated functions under kernel check condition.
