Revert "e2fsprogs: fix posix_fadvise() signature mismatch"

This reverts commit c3d690166c.

The real cause of problem is missing posix_fadvise() implementation in uClibc
for xtensa. This has now been fixed with the uclibc version bump. The internal
e2fsprogs posix_fadvise() implementation is broken on 32bit systems anyway, and
upstream has removed it.

-MIME-Version: 1.0

-uClibc declares posix_fadvise() even when the architecture does not provide
-one. The static posix_fadvise() signature is not compatible with POSIX. Rename
-the internal implementation to fix this. Fixes the following build failure
-when building against uClibc:
-
-e4defrag.c:189:2: warning: #warning Using locally defined posix_fadvise interface. [-Wcpp]
-e4defrag.c:203:12: error: conflicting types for ‘posix_fadvise’
-
-Patch status: sent upstream
