Fix for MOUNTPOINT missing in output of lsblk command

[AkshaySainiDell]

Description

In util-linux 2.37.4-11.el9_2, the lsblk command did not include MOUNTPOINT field in its output. This field is required in getMountInfoFromDevice method; without this the code breaks with below error

panic: runtime error: index out of range [1] with length 1

goroutine 60 [running]:
github.com/dell/gofsutil.(*FS).getMountInfoFromDevice(0x0?, {0x1fde490, 0xc000681800}, {0xc0005380a8, 0x11})
	/root/Projects/Proj1/pkg/mod/github.com/dell/[email protected]/gofsutil_mount_linux.go:467 +0xe3f

In this PR, we have modified the lsblk command to consistently include the necessary fields, including 'MOUNTPOINT', in its output. This resolves the issue and ensures the code operates as expected.
