fs/gfs2: Use the enum req_op and blk_opf_t types 

Improve static type checking by using the enum req_op type for variables
that represent a request operation and the new blk_opf_t type for
variables that represent request flags. Combine the first two
gfs2_submit_bhs() arguments into a single argument.
