BACKPORT qed: Fix copying 2 strings

The strscpy() was a recent fix (net: qed: use correct strncpy() size) to
prevent passing the length of the source buffer to strncpy() and guarantee
null termination.
It misses the goal of overwriting only the first 3 characters in
"???_BIG_RAM" and "???_RAM" while keeping the rest of the string.
Use strncpy() with the length of 3, without null termination.

qed: Backport Free RoCE ILT Memory on rmmod qedr

Rdma requires ILT Memory to be allocated for it's QPs.
Each ILT entry points to a page used by several Rdma QPs.
To avoid allocating all the memory in advance, the rdma
implementation dynamically allocates memory as more QPs are
added, however it does not dynamically free the memory.
The memory should have been freed on rmmod qedr, but isn't.
This patch adds the memory freeing on rmmod qedr (currently
it will be freed with qed is removed).

An outcome of this bug, is that if qedr is unloaded and loaded
without unloaded qed, there will be no more RoCE traffic.

The reason these are related, is that the logic of detecting the
first QP ever opened is by asking whether ILT memory for RoCE has
been allocated.
