Subject: [PATCH][V2] xfs: remove redundant pointer lip

The assignment to pointer lip is not really required, the pointer lip
is redundant and can be removed.

Cleans up clang-scan warning:
warning: Although the value stored to 'lip' is used in the enclosing
expression, the value is never actually read from 'lip'
[deadcode.DeadStores]

V2: Keep != NULL comparison for stylistic reasons, as suggested by
    Darrick J. Wong
