cam(4): Fix some warnings

Browse Source 
When bcopy is treated as memcpy/memmove, Clang produces warnings that the
size argument doesn't match the type of the source.  This is true, it
doesn't match; we're aliasing the source.

Explicitly cast the source pointer to the expected type to remove the
warning.

No functional change.
