Modified Files:
	syssrc/sys/arch/mips/mips: pmap.c

Log Message:
The previous microscale optimazation in pmap_asid_alloc() was
half-baked and resulted in one superfluous ASID bump if new pmaps
are created when pmap_asid_generation > 0.   Need to initialize pmap
fields correctly.

Yet, this possibly might not be the perfect solution.  If one
process bumped pmap_asid_generation _after_ a new pmap was created
and initialized with then-current pmap_asid_generation value.  In
that case, the new pmap would have another (superfluous) ASID bump
when 2nd (not 1st) CPU tick is assigned.  I'm not sure if this case
would happen.

Have pmap_max_asid variable to hold the maximum number of ASID
(TLBpid) supported by processor anticipating the possible runtime
