[dpdk-stable] [PATCH v2 2/5] net/hns3: fix build with sve enabled

[Ruifeng Wang]

Building with SVE extension enabled stopped with error:

 error: ACLE function ‘svwhilelt_b64_s32’ requires ISA extension ‘sve’
   18 | #define PG64_256BIT  svwhilelt_b64(0, 4)

This is caused by unintentional cflags reset.
Fixed the issue by appending required flag to cflags instead of
overriding it.
