[PATCH c++ 07/12] gdbscm_memory_port_write: use local variable to avoid adding casts

[Simon Marchi <simon dot marchi at polymtl dot ca>]

By having a local variable of type (const gdb_byte *), we can avoid adding
two casts.

gdb/ChangeLog:

	* guile/scm-ports.c (gdbscm_memory_port_write): Declare new
	"data" local variable and use it.
