[PATCH v2] net/smc: Replace use of strncpy on NUL-terminated string with strscpy

[James Flowers <bold.zone2373@fastmail.com>]

strncpy is deprecated for use on NUL-terminated strings, as indicated in
Documentation/process/deprecated.rst. strncpy NUL-pads the destination
buffer and doesn't guarantee the destination buffer will be NUL
terminated.

V1 -> V2: Replaced with two argument version of strscpy
Note: this has only been compile tested.
