docs: block: fix discard_max_bytes references

Browse Source 
When discard_max_hw_bytes was introduced, in commit 0034af0365
("block: make /sys/block/<dev>/queue/discard_max_bytes writeable"),
the discard_max_bytes documentation section was renamed to
discard_max_hw_bytes, but the references it contains to
discard_max_bytes weren't updated.

This patch refers to discard_max_hw_bytes instead. It also reflows the
paragraph so that sentences end lines.

Devices that support discard functionality may have internal limits on
the number of bytes that can be trimmed or unmapped in a single operation.
The discard_max_bytes parameter is set by the device driver to the maximum
number of bytes that can be discarded in a single operation. Discard
requests issued to the device must not exceed this limit. A discard_max_bytes
value of 0 means that the device does not support discard functionality.
