qcacld-3.0: Fix 32 bit compilation in IPA path

Compilation error is seen for 32 bit builds in htt_tx_ipa_uc_wdi_tx_buf_alloc
as buffer_paddr, which is defined as unsigned long and will be a 32 bit bit
variable for 32 bit builds, is right shifted by 32 to get the high 32 bits
for fragment descriptor.

Instead of right shifting buffer_paddr by 32, use APIs lower_32_bits
and upper_32_bits.
