runtime: avoid zeroing hmap fields in makemap twice
Stack allocated hmap structs are explicitly zeroed before being
passed by pointer to makemap.
Heap allocated hmap structs are created with newobject
which also zeroes on allocation.
Therefore, setting the hmap fields to 0 or nil is redundant
since they will have been zeroed when hmap was allocated.
