[mpd-devel] [PATCH] ReusableArray: fix build error on GCC7

[Ben Boeckel]

GCC7 outputs the following error without this change:

src/util/ReusableArray.hxx:61:35: error: no matching function for call to ‘swap(size_t&, const size_t&)’
std::swap(capacity, src.capacity);

which can be resolved by just using an rvalue-reference rather than a
const rvalue-reference.
