ShellPkg: fix display for map command with filtering

This patch correctly displays map information when a filter was applied such as “map fs*” or “map f*”, including the use of “-c” to display the consist names first in this situation.

It also moves a statement from both clauses of an “if/else” to above the “if” statement for efficiency.
