[PATCH v4 31/45] fs: fat: Shrink the size of a few strings

[Simon Glass]

To save a few bytes, replace Error with ** and try to use the same string
for multiple messages where possible.

Signed-off-by: Simon Glass <sjg at chromium.org>

(no changes since v2)

Changes in v2:
- Drop ** in strings and use log_err() for messages
