vfs_glusterfs: Retrieve fs capabilities using vfs_get_fs_capabilities

vfs_glusterfs is supposed to be the last entry when listed with
other vfs modules. This is due to the fact that the connection path
is not local to the server but relative to the virtual remote file
system beneath it. Especially SMB_VFS_FS_CAPABILITIES implementation
from vfs_default is likely to return incorrect results based on the
connection path assumed to be local to the server which might not be
the case with glusterfs module stacked. Therefore it doesn't make sense
to pass through any vfs interface implementations further down the line
to vfs_default.

Instead make use of get_fs_capabilties to start with already known fs
capabilties from connect phase.
