sh: Prevent fixed slot PMB remapping from clobbering boot entries.
The PMB initialization code walks the entries and synchronizes the software PMB state with the hardware mappings, preserving the slot index. Unfortunately pmb_alloc() only tested the bit position in the entry map and failed to set it, resulting in subsequent remaps being able to be dynamically assigned a slot that trampled an existing boot mapping with general badness ensuing.
