Subject: net: Change skb_ensure_writable()'s write_len param to unsigned int
 type
Patch-mainline: v5.19-rc1
Git-commit: 92ece28072f18f30099770c5d4b8e300ea6820fa
References: jsc#PED-1377

Both pskb_may_pull() and skb_clone_writable()'s length parameters are of
type unsigned int already. Therefore, change this function's write_len
param to unsigned int type.
