Authored by Steven Whitehouse

Exists in master and in 4 other branches v3.2_AM335xPSP_04.06.00.11, v3.2_NEWT335xPSP_04.06.00.11, v3.2_SBC_SMARTMEN, v3.2_SMARCT335xPSP_04.06.00.11

[GFS2] Fix uninitialised variable 

This fixes a bug where, in certain cases an uninitialised variable
could cause a dereference of a NULL pointer in gfs2_commit_write().
Also a typo in a comment is fixed at the same time.
