Commit 752614cab8 ("target/riscv: rvv: Add tail agnostic for vector
load / store instructions") added code to set the tail elements to 1 in
the end of vext_ldst_stride(), vext_ldst_us(), vext_ldst_index() and
vext_ldff(). Aside from a env->vl versus an evl value being used in the
first loop, the code is being repeated 4 times.
Create a helper to avoid code repetition in all those functions.
Arguments that are used in the callers (nf, esz and max_elems) are
passed as arguments. All other values are being derived inside the
helper.

A common trend in this file is to retrieve a RISCVCPU pointer by first
retrieving a CPUState pointer via env_cpu(). The CPU pointer is used
only to access the RISCVCPUConfig object and nothing else.
Let's use riscv_cpu_cfg() to access what we need directly without these
2 pointers.
