Stop taking TARGET_VIRT_ADDR_SPACE_BITS into account.
Since we currently bound CPU_TLB_DYN_MAX_BITS to 22,
the new bound with a 4k page size is 20, which isn't
so different.

Block devices that don't support discard have a discard_granularity of
0. Currently, this results in a division by zero when we try to make
sure that it's a multiple of request_alignment. Only try to update
bs->bl.pdiscard_alignment when we got a non-zero discard_granularity
from sysfs.
