net: hns3: clean up a type mismatch warning

Browse Source 
[ Upstream commit e79c0e324b011b0288cd411a5b53870a7730f163 ]

abs() returns signed long, which could not convert the type
as unsigned, and it may cause a mismatch type warning from
static tools. To fix it, this patch uses an variable to save
the abs()'s result and does a explicit conversion.
