Subject: osd/OSD.h: move shared_ptr instead of copying it
X-Git-Tag: v11.0.0~624^2

osd/OSD.h: move shared_ptr instead of copying it

By copying map to next_osdmap we are increasing the shared_ptr's
reference count, which is then decreased again when map variable goes
out of scope. This can be avoided by using std move.
