The variable 'error' is being assigned a value that is never read,
the assignment and the variable and redundant and can be removed.
Cleans up clang scan build warning:

fs/dax.c:1880:10: warning: Although the value stored to 'error' is
used in the enclosing expression, the value is never actually read
from 'error' [deadcode.DeadStores]
