jfs: fix bogus variable self-initialization
A statement was originally added in 2006 to shut up a gcc warning,
now but now clang warns about it:
fs/jfs/jfs_txnmgr.c:1932:15: error: variable 'pxd' is uninitialized when used within its own initialization
[-Werror,-Wuninitialized]
pxd_t pxd = pxd; /* truncated extent of xad */
~~~ ^~~
Modern versions of gcc are fine without the silly assignment, so just
drop it. Tested with gcc-4.6 (released 2011), 4.7, 4.8, and 4.9.
Fixes: c9e3ad6021e5 ("JFS: Get rid of "may be used uninitialized" warnings")
