rpmsg: Use strscpy() instead of strscpy_pad()

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

kzalloc() already zero-initializes the destination buffer, making
strscpy() sufficient for safely copying the name. The additional NUL-
padding performed by strscpy_pad() is unnecessary.

The size parameter is optional, and strscpy() automatically determines
the size of the destination buffer using sizeof() when the argument is
omitted. RPMSG_NAME_SIZE is equal to sizeof(rpdev->id.name) and can be
removed - remove it.

No functional changes intended.
