kconfig: sym_expand_string_value: allow for string termination when reallocing
When expanding a parameterised string we may run out of space, this triggers a realloc. When computing the new allocation size we do not allow for the terminating '\0'. Allow for this when calculating the new length. Signed-off-by: Andy Whitcroft <apw@canonical.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
