[PATCH] 2.6.21: nfs_readpages: Add missing braces

["Maciej W. Rozycki" <macro@linux-mips.org>]

 A change a while ago added a call to gather statistics to a conditional 
statement, but braces were missed on that occasion resulting in a change 
of semanticts.  This a change to rectify.

 It should be obvious -- please apply.
